Boot from FC SAN CentOS 5.1 x86-64
by nate 18 Mar '08

18 Mar '08

Anything special needed to boot from a SAN in CentOS 5.1 x86-64 ? We have a new system running a QLA2342 FC HBA connected to a SAN, have a volume exported to it and would like to boot from it. We PXEboot kickstart and that works, the installer sees the disk, installs to it, and reboots. When GRUB tries to load all it prints is "GRUB" and sits there. When we try the Xen edition of CentOS 5.1, when GRUB tries to load the screen goes black and the system reboots. When we try VMWare ESX 3.5.0 it works perfectly, so the BIOS configurations and the SAN config is good, something specific with CentOS 5.1. I see in the release notes that SAN boot is supported, but doesn't give any special instructions. Anyone else booting CentOS directly from a FC SAN ? Any special considerations needed for multipathing and stuff when booting ? thanks nate

CentOS 4.5 - Apache 2.0.52
by Tom Brown 17 Mar '08

17 Mar '08

Hi does the stock apache in CentOS 4.5 - ie 2.0.52 come compiled in 'Pre-Fork' mode? I ask as we have an app that needs to run against apache and this needs to run in 'Worker Mode' as opposed to 'Pre Fork' If this is the case then i guess i will need to rebuild it from the .src.rpm but can anyone let me know for sure? thanks

Running CentOS 4.6 domUs on CentOS 5.1 dom0 and domUs crash
by Nathan Grennan 17 Mar '08

17 Mar '08

I have a CentOS 5.1 dom0 running on a machine with two cores and 4gb of memory. It runs three 4.6 domUs and one 5.1 domU. Just out of the blue the other night all the 4.6 domUs crashed, but the dom0 stayed up. I ran xm console (domU-name) and got the Oops information below. I didn't get anything from the 5.1 domU. I think it had been rebooted a few days before and hadn't come up because of a initrd issue.

CDRW-DVD Mount Problem, Centos 5.1, Intel board...
by Pam Astor 17 Mar '08

17 Mar '08

I'm having a problem mounting my new CDRW DVD in my new machine I just built. The motherboard is an Intel DP35DP, and I connected the CDRW DVD via ribbon cable into the motherboard IDE slot. Centos 5.1 is installed and functioning fine so far (other than this problem). I can't mount the CDRW-DVD unit. I was able to run cdrecord with the command: cdrecord -v speed=2 dev=6,0,0 -data /home/mydir/Desktop/backup_bootimage.iso to copy a file that I downloaded, apparently the data copy went fine, but when I ejected the CD and then tried to re mount the same CD to read the file, it would not mount. So then I tried mounting the Centos 5.1 distro disk that I used to install the OS, and am having the same problem with the distro disk. If anyone could give me some suggestions or insights I'd appreciate it. I have provided some data below. I tried the below commands after ejecting the CD and then executing the commands while the drawer is open, and I got the below outputs: # sudo mount -t iso9660 /dev/sr0 /mnt/cdrom mount: special device /dev/sr0 does not exist And: # mount /dev/cdrom /mnt/cdrom mount: block device /dev/cdrom is write-protected, mounting read-only mount: you must specify the filesystem type And: # mount /dev/scd0 /mnt/cdrom mount: block device /dev/scd0 is write-protected, mounting read-only mount: you must specify the filesystem type And: #sudo mount -t iso9660 /dev/scd0 /mnt/cdrom mount: block device /dev/scd0 is write-protected, mounting read-only mount: wrong fs type, bad option, bad superblock on /dev/scd0, missing codepage or other error In some cases useful info is found in syslog - try dmesg | tail or so And: sudo mount -t iso9660 /dev/scd0 /mnt/cdrom -o ro,unhide mount: wrong fs type, bad option, bad superblock on /dev/scd0, missing codepage or other error In some cases useful info is found in syslog - try dmesg | tail or so And: sudo mount -t iso9660 /dev/sr0 /mnt/cdrom -o ro,unhide mount: special device /dev/sr0 does not exist Here is info from cat /etc/fstab, cat /proc/mounts, fdisk -l, and cdrecord -scanbus and dmesg | grep -i -e CD -e CD-ROM respectively: >From cat/etc/fstab: /dev/VolGroup00/LogVol00 / ext3 defaults 11 LABEL=/boot /boot ext3 defaults 1 2 tmpfs /dev/shm tmpfsdefaults 0 0 devpts /dev/pts devpts gid=5,mode=620 0 0 sysfs/sys sysfs defaults 0 0 proc /proc proc defaults 00 /dev/VolGroup00/LogVol01 swap swap defaults 0 0 >From cat /proc/mounts: [root@localhost/]# cat /proc/mounts rootfs / rootfs rw 0 0 /dev/root / ext3rw,data=ordered 0 0 /dev /dev tmpfs rw 0 0 /proc /proc proc rw0 0 /sys /sys sysfs rw 0 0 none /selinux selinuxfs rw 00 /proc/bus/usb /proc/bus/usb usbfs rw 0 0 devpts /dev/ptsdevpts rw 0 0 /dev/sda1 /boot ext3 rw,data=ordered 0 0 tmpfs/dev/shm tmpfs rw 0 0 none /proc/sys/fs/binfmt_misc binfmt_misc rw0 0 sunrpc /var/lib/nfs/rpc_pipefs rpc_pipefs rw 00 /etc/auto.misc /misc autofsrw,fd=6,pgrp=2758,timeout=300,minproto=5,maxproto=5,indirect 00 -hosts /net autofsrw,fd=11,pgrp=2758,timeout=300,minproto=5,maxproto=5,indirect 00 fdisk -l Disk /dev/sda: 500.1 GB, 500107862016bytes 255 heads, 63 sectors/track, 60801 cylinders Units =cylinders of 16065 * 512 = 8225280 bytes Device Boot Start EndBlocks Id System /dev/sda1 * 1 13 104391 83 Linux /dev/sda2 1460801 488279610 8e Linux LVM Disk /dev/sdb: 500.1 GB,500107862016 bytes 255 heads, 63 sectors/track, 60801cylinders Units = cylinders of 16065 * 512 = 8225280 bytes DeviceBoot Start End Blocks Id System /dev/sdb1 * 1 60801 488384001 8eLinux LVM >From cdrecord -scanbus: scsibus6: 6,0,0 600) 'TSSTcorp''CDDVDW SH-S202J ' 'SB00' Removable CD-ROM 6,1,0 601) * 6,2,0602) * 6,3,0 603) * 6,4,0 604) * 6,5,0 605) * 6,6,0 606)* 6,7,0 607) * >From dmesg | grep -i -e CD -e CD-ROM: [root@localhost etc]# dmesg | grep -i -e CD -e CD-ROM uhci_hcd 0000:00:1a.0: UHCI Host Controller uhci_hcd 0000:00:1a.0: new USB bus registered, assigned bus number 1 uhci_hcd 0000:00:1a.0: irq 193, io base 0x000030e0 uhci_hcd 0000:00:1a.1: UHCI Host Controller uhci_hcd 0000:00:1a.1: new USB bus registered, assigned bus number 2 uhci_hcd 0000:00:1a.1: irq 74, io base 0x000030c0 uhci_hcd 0000:00:1a.2: UHCI Host Controller uhci_hcd 0000:00:1a.2: new USB bus registered, assigned bus number 3 uhci_hcd 0000:00:1a.2: irq 177, io base 0x000030a0 uhci_hcd 0000:00:1d.0: UHCI Host Controller uhci_hcd 0000:00:1d.0: new USB bus registered, assigned bus number 4 uhci_hcd 0000:00:1d.0: irq 82, io base 0x00003080 uhci_hcd 0000:00:1d.1: UHCI Host Controller uhci_hcd 0000:00:1d.1: new USB bus registered, assigned bus number 5 uhci_hcd 0000:00:1d.1: irq 201, io base 0x00003060 usb 2-1: new low speed USB device using uhci_hcd and address 2 uhci_hcd 0000:00:1d.2: UHCI Host Controller uhci_hcd 0000:00:1d.2: new USB bus registered, assigned bus number 6 uhci_hcd 0000:00:1d.2: irq 193, io base 0x00003040 ohci_hcd: 2005 April 22 USB 1.1 'Open' Host Controller (OHCI) Driver (PCI) ehci_hcd 0000:00:1a.7: EHCI Host Controller ehci_hcd 0000:00:1a.7: new USB bus registered, assigned bus number 7 ehci_hcd 0000:00:1a.7: debug port 1 ehci_hcd 0000:00:1a.7: irq 177, io mem 0xe3225c00 ehci_hcd 0000:00:1a.7: USB 2.0 started, EHCI 1.00, driver 10 Dec 2004 ehci_hcd 0000:00:1d.7: EHCI Host Controller ehci_hcd 0000:00:1d.7: new USB bus registered, assigned bus number 8 ehci_hcd 0000:00:1d.7: debug port 1 ehci_hcd 0000:00:1d.7: irq 82, io mem 0xe3225800 ehci_hcd 0000:00:1d.7: USB 2.0 started, EHCI 1.00, driver 10 Dec 2004 usb 2-1: new low speed USB device using uhci_hcd and address 3 usb 3-2: new low speed USB device using uhci_hcd and address 2 Vendor: TSSTcorp Model: CDDVDW SH-S202J Rev: SB00 Type: CD-ROM ANSI SCSI revision: 05 sr0: scsi3-mmc drive: 48x/48x writer dvd-ram cd/rw xa/form2 cdda tray Uniform CD-ROM driver Revision: 3.20 sr 6:0:0:0: Attached scsi CD-ROM sr0 cdrom: This disc doesn't have any tracks I recognize!

Centos 5.1 installation problems -- couldn't find devices
by Yu-Hui Jin 17 Mar '08

17 Mar '08

Hi, there, I just bought a Dell Inspiron 530 with the following basic configuration: Inspiron 530 Intel Core2 processor Q6600 (2.40Ghz 1066FSB) w/Quad Core Technology and 8MB cache SATA 0: Samsung HD501LJ (500GB Serial ATA II Hard Drive(7200RPM)) SATA 1: PDBS DVD +/- RW DH-16W1S (16X DVD+/-RW Drive) I tried to install Centos 5.1 on it with dual boot (keep Windows XP partition) and got stuck on some strange issues. I hope one of you could shed some light on what I should do next. Here's the summary of my installation attempts. Attempt 1: I burned both an installation DVD (slow and verified) and installation CD #1. I tried them both and both failed due to no driver found. More specifically, at the step for "what type of media contains the packages to be installed?", I chose "Local CDROM", the result screen said "No driver found" and prompted me to Select driver from a list of drivers. I randomly chose a few but none worked. Attempt 2. I tried network installation. I chose "HTTP" when prompted for the media. I then specified the mirror.centos.org<http://mirror.centos.org/centos/5/os/i386/>as the Web Site Name and /centos/5/os/i386/ <http://mirror.centos.org/centos/5/os/i386/> as the Red Hat directory. It got the installation started successfully. However, at the step for partitioning the disk, I was prompted to choose the partition option and I checked the "review and modify partitioning layout". Also, there's no drive shown in the "select the drive(s) to use for this installation" panel. When i clicked Next, a "No drives Found" message popped up, saying "an error has occurred -- no valid devices were found on which to create new file systems. please check your hardware for the cause of this problem." It seemed both attempts failed due to the installation program couldn't find either the SATA DVD drive or the SATA hard disk. However, it's hard to believe Centos 5.1 installation couldn't recognize these two SATA devices. I'm now stuck. Any suggestion or advice is much appreciated. -- Regards, -Hui

10Gbit ethernet
by Jake Grimmett 17 Mar '08

17 Mar '08

If I could ask question about 10Gbit ethernet.... We have a 70 node cluster built on Centos 5.1, using NFS to mount user home areas. At the moment the network is a bottleneck, and it's going to get worse as we add another 112 CPUs in the form of two blade servers. To help things breath better, we are considering building three new NFS servers, and connecting these and the blade servers directly via 10Gbit to a new core switch, the older nodes will stay with 1Gbit ethernet, but be given new switches uplinked via 10Gbit to the core switch. Before I spend a great deal of money, can I ask if anyone here has experience of 10GBit? Dell, HP, Supermicro, IBM (etc..) seem to be pushing the NetXen PCIe cards, so I guess these drivers work...? As to media, although CX4 seems cheaper than optical, I hear the cabling is nasty. And is the magical fairy going to fix 10Gbit over cat6A anytime soon? any thoughts appreciated. Jake --

internal messages problem with postfix
by Mufit Eribol 17 Mar '08

17 Mar '08

Hello, After a server crash, I re-installed postfix, cyrus-imapd, amavisd-new, spamassassin on a Centos 5.1 box. But, now mail system behaves somewhat different. There is no problem with mail receiving/sending from/to internet. Before the crash, mail system used to sent internal messages to root(a)example.com. But now, I can't receive internal messages as it tries to send them to root(a)server.example.com. I used the same postfix, cyrus-imapd, amavisd-new, /etc/aliases conf files from the previous setup. Must be a configuration issue I overlook. Could anybody please tell me what to check? Best wishes, Mufit main.cf: mydomain = example.com myhostname = server.example.com mydestination = example.com ... amavisd.conf $mydomain = 'example.com'; $myhostname = 'server.example.com';

MySQL 4.1 on Centos 5 ?
by Sergej Kandyla 17 Mar '08

17 Mar '08

Hi All, Could anyone tell me, how to correctly install MySQL4.1 on Centos 5 ? By default Centos 5 comes with mysql5… If I will compile mysql4 from sources to separate prefix, some features may be unavailable (unix sockets for example). I’m moving some critical application (online booking) based on java, tomcat5, mysql4.1 from old server fedora 4 to new server running Centos 5. So, I don’t want update mysql to new version this time. Thanks, SK

Partition/filesystem expansion difficulties
by Hugh E Cruickshank 17 Mar '08

17 Mar '08

CentOS 4.6 Hi All: I am now officially stumped. I have tried everything that can think of and I have googled until I am blue in the face and tried just about everything that I could find that looked the least bit like it might apply and still no (or at least partial) joy. I am going to cram as much information into this email as I can and hope that someone out there can either tell me what I am doing wrong or point me in a new direction for research. The hardware: We have an Acer G700 server which comes with 8 internal hot swap SCSI bays connected to an Adaptec SCSI HBA. There are two banks of 4 drives connect to each of the two channels of the Adaptec HBA. To this we have added an IBM EXP400 external array with 12 hot swap SCSI drives connected to an LSI MegaRAID HBA. 36GB drives were used throughout. The external drives were configured as 6 mirror pairs through the MegaRAID BIOS. The OS install: When I installed CentOS 4 originally I allowed the installer to configure the 8 internal drives with software mirroring and the external drives as a striped set effectively making the external disk array a RAID 10 array. The original problem: Our boot drive failed which did not cause an immediate problem as the system kept on running. The real problem was that I had already used all the spare drives I had on-hand and I could not source a replacement drive that matched on size and speed (10K). The original solution: I then had what I thought was a good idea and I purchase three 146GB 10K drives. I would replace the two 36GB drives used in the system mirrored pair with 146GB drives and have one 146GB spare. I would then be able to free up a 36GB to use as a spare for the other three pairs of drives. This proved to be easier said then done but I did eventually get it done by using Norton Ghost to copy the good mirrored 36GB drive on to two of the 146GB drives and then using grub to install the bootloader (which I found out the hard way is NOT installed on the mirrored drive - ARGHHHHHH!). However I did get it done but with one minor problem. The current problem: The two 146GB drives are now partitioned as 36GB and I want to expand the partitions and the installed filesystems to use the additional space available on the drives. The current partition looked like: Device Boot Start End Blocks Id System /dev/sda1 * 1 64 514048+ fd Linux raid autodetect /dev/sda2 65 1084 8193150 fd Linux raid autodetect /dev/sda3 1085 1339 2048287+ fd Linux raid autodetect /dev/sda4 1340 4462 25085466 f W95 Ext'd (LBA) /dev/sda5 1340 4462 25085466 fd Linux raid autodetect No problem I thought and proceeded make a Ghost copy of the boot drive and then used PartedMagic to expand both the last physical and logical partitions and the resident ext3 files system. Lucky thing I mad that Ghost copy and the filesystem turned out to be corrupt (could not find the super block). Restored from the backup. I then tried using PartedMagic to expanding just the last physical partition and that worked. The current fdisk for both sda and sde looks like: Device Boot Start End Blocks Id System /dev/sda1 * 1 64 514048+ fd Linux raid autodetect /dev/sda2 65 1084 8193150 fd Linux raid autodetect /dev/sda3 1085 1339 2048287+ fd Linux raid autodetect /dev/sda4 1340 17849 132616575 f W95 Ext'd (LBA) /dev/sda5 1340 4462 25085466 fd Linux raid autodetect I then tried to use resize2fs to expand the files systems but that did on work. No error, it just report that the filesystems were already at the full size. Today I tried to use: mdadm --grow /dev/md3 --size=max resize2fs /dev/md3 but again no joy (md3 is the filesystem in sda5/sde5). No errors but no change either. I even thought to look at LVM but, as far as I can tell, that is not being used in our case (all drives are listed and unregistered). The plea: If anyone has any thoughts on what I have been doing wrong or a new direction that I can research I would really appreciate it. From everything that I have read this should be doable. My next step is to backup the contents of the filesystem and then delete it, re-create it and restore the backup. If that is the only way of doing this then I will gladly do it but I still think I should be able to expand it in-place (just call me stubborn). TIA Regards, Hugh -- Hugh E Cruickshank, Forward Software, www.forward-software.com

Running network services as a non-root user
by David Hláčik 17 Mar '08

17 Mar '08

Hi, I am using open source Alfresco( alfresco.com ), written in java, which has own code for FTP, CIFS (running on tomcat apache and java). I need to run tomcat5 as root in order to achieve that alfresco will bind ftp cifs on privileged ports (21 , 135 .). I am wondering, it is possible to allow user to bind on some privilleged port. Like having whole alfresco running under user alfresco and not root and able to bind on privileged ports? CentOS 5.1 Thanks! David

what should I do?
by Sobari Tanuwijaya 17 Mar '08

17 Mar '08

Dear All, a friend of mine who has a small office want to have a configuration like this: * around 3 people can have full access to internet * around 1-2 people can just have email access (can send and receive email to any address) * the rest of the people in the company just can have internal email (can send and receive email just to/from the peer - on the same domain). I think I can use the squid to prevent the access using the browser, but what should I do to set the email configuration like that? I think I can install qmail for the MTA, but I don't know how to prevent several person just can send/receive email from the same domain, while the other can send/receive email to any address he wants to. Anybody kind enough to share how to do that? Thanks in advance for you help. -- Tanu --

Firefox 3
by Niki Kovacs 17 Mar '08

17 Mar '08

Hi, I just read the release announcement for RHEL 5.2beta: https://www.redhat.com/archives/rhelv5-announce/2008-March/msg00000.html And something caught my eye: --8<----------------------------------------- * Laptop and Desktop Enhancement + Suspend and Hibernate improvements + Re-base of the top Desktop applications - Evolution 2.12.3 - Firefox 3 - OpenOffice 2.3.0 - Thunderbird 2.0 + Updated graphics drivers --8<----------------------------------------- I see that the folks from Red Hat decided to completely ignore Firefox 2.0: an eloquent detail. Now it's more than once that I've read good things about Firefox 3. Much less RAM-hungry than it's predecessors, excellent standards compliance, much more stable. What's the best way to get Firefox 3 on my CentOS 5.1? Is there some RPM for RHEL somewhere? Some SRPM? Or simply wait patiently for CentOS 5.2? Aside: I use XFCE, not GNOME, so I don't have to go through the chore of updating some core GNOME components (like Yelp). Cheers, Niki

Backup Question
by Joseph L. Casale 16 Mar '08

16 Mar '08

We are migrating an LTO2 library off Veritas and NTBackup on a Windows Server to a Linux Server with either Bacula or Amanda. Originally, the Windows server used scripts to sync changes from various other Windows servers using Robocopy to a locally attached set of volumes, then ran the backup nightly (Full's were always done). I now had hoped to rsync the Samba shares to a local replica on the Linux Server and then start the backup every night after it finishes. Would this be the most efficient way to do this, or are there better tools for this? I need an additional replica of the data, so using the Windows Bacula client doesn't help, and I must be able to only replicate the changes or I'll miss my backup window based on the volume of data. Thanks for any suggestions, jlc

If the machine panics at boot time, there is a good chance that you installed with LVM and its got both the drives into one volume. You will need to reinstall that second harddrive, then work out the process of shrinking the filesystem down to only 1 drive, then remove the second drive. The scope of this work might be too much for an email, so I can best point you at the LVM HowTo. There are also some good lvm tips in the CentOS5 docs ( http://www.centos.org/docs/5/ ) OK this is what I have when I run mount - does it appear that I have both drives on one volume?:  /dev/mapper/VolGroup00-LogVol00 on / type ext3 (rw) proc on /proc type proc (rw) sysfs on /sys type sysfs (rw) devpts on /dev/pts type devpts (rw,gid=5,mode=620) /dev/sda1 on /boot type ext3 (rw) tmpfs on /dev/shm type tmpfs (rw) none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw) sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw) ____________________________________________________________________________________ Be a better friend, newshound, and know-it-all with Yahoo!

Un Installing a hard drive in a Centos 5.1 box
by Pam Astor 16 Mar '08

16 Mar '08

Hi Guys, I'm fairly new to Linux and I'm trying to un install a hard drive from my Centos 5.1 box running KDE. When I built the PC, I installed two 500 gig maxtors in the tower, then I installed Centos. Now I've decided that I want to remove the slave drive and use it as an external backup drive - I am mounting it into one of those external drive cases with a built in fan. When I physically removed the drive and restarted the PC, centos would not boot up and went into a kernel panic. I'm sure I'm supposed to somehow unmount the thing before I do this, and that's my question - how do I un-install the hard drive - software wise - so that on next boot up, centos don't go crazy looking for it? ____________________________________________________________________________________ Be a better friend, newshound, and know-it-all with Yahoo!

My belief is that what you wrote is dead accurate, with regard to many things and once I get the Sound working properly, I will try to get rid of what I know I am not using. However, with regard to web browsers, as one example, I find that having both Firefox and Konqueror is necessary at this time. Firefox, with the settings as liberal as I can make them, does not work properly for me, when I access Gmail on the web. Konqueror, which Gmail shows is not fully supported and does not allow access to all Gmail features on the web, works much better than Firefox there. A former Supervisor and Colleague, who uses Ubuntu, has no problem using Gmail on the web, with a later version of Firefox. OT: From what you and Dag wrote about Firefox 3, I will upgrade from CentOS 5 to 5.2, when I can get the DVD! > I've been a long-time Slackware user, and Slackware has one guiding > principle: KISS - Keep It Simple Stupid!

And one mixer app: alsamixer (I uninstalled xfce4-mixer). I install both GNOME (which I use 95% of the time) and KDE when I do clean installs. Once, I had GNOME corrupted, and I used KDE, temporarily, to keep going. KDE has many many more things than GNOME. I always use K3b and there are some other KDE Applications and Utilities that I use occasionally. > So what you could do to make things easier: establish which sound system > and sound mixer app you are using. And then get rid of the unused ones. After I find the solution to the problem, I will try to do that! It is my understanding and belief that Front Ends (GUI or Text based) that modify Linux Configuration files may do so in different ways. If the file is simple, I modify with a Text editor. One experience I had, with system-config-display (?) was that it said it was writing a new Xorg file, but, in fact, it did not. Someone else posted in this ML and Johnny or Jim said to use the command with -- rewrite or something I can't remember, as I write this. One of the things about Webmin, is that supposedly one can use it to modify Configuration files, or do it manually with a Text editor, without screwing things up. I will keep working on this microphone audio problem and if I cannot solve it, then I will post in the alsa-user at lists.sourceforge.net as Anne suggested yesterday, in 2 or 3 days! Thanks again!

clarifications

Hello all, I've been trying to get spamassassin and clamav working, but got really confused when I realized there are various incarnations of the software. Originally, I started out with just spamassassin, but learned there is also an SA-milter. Can someone tell me which of the various spam fighting packages i.e., sa, sa-milter, clamav, clamave-milter, and so forth? I ran into problems with one package with the system not being able to open a socket, so I just gave up. I hope I'm not too vague here, but essentially, I just would like to know what the milter part does, and if that's the way to go, or the non-milter versions. I'm subscribed via digest, and if it's not too much trouble, I'd appreciate a cc direct to me. Many thanks.. Sam

I use their test robot to test, but when I try it with Skype for Linux, when they are going to playback what I speak into the microphone, there's one beep and then almost immediately, a 2nd beep.

You said you have 4 hard disks. Make a software RAID1 out of the first two. Make a software RAID1 out of the second two and your good to go. You can use dump/restore to backup the logical volumes on the second RAID set to an LV on the first. No need for bare metal restore. Just need to get some working Linux distro to be able to read your files. Going HW RAID for your desktop is going to get in the way of you getting things going and if your HW RAID card fails then what? Your drives will only work with another identical HW RAID card. -Ross ----- Original Message ----- From: centos-bounces(a)centos.org <centos-bounces(a)centos.org> To: CentOS mailing list <centos(a)centos.org> Sent: Fri Mar 14 09:08:39 2008 Subject: RE: [CentOS] Recommendations for a â€œreal RAID" 1 card on Centos box >>> You can turn on write back caching if you have a UPS as well >>> (provided your UPS is wired into your system for a graceful shutdown) >>> >> >> Hopefully you have a redundant PS unit.

As an alternative to RAID1 for a mission critical desktop machine @ home, what would you reccomend? Maybe a bare metal restore solution able to restore to different hardware, (i.e. if a motherboard dies and drive crashes due to power spike or some catastrophe, I'm screwed if I can't find the exact same make - model)? _________________________________________________________________ Connect and share in new ways with Windows Live. http://www.windowslive.com/share.html?ocid=TXT_TAGHM_Wave2_sharelife_012008 ------------------------------ Message: 8 Date: Fri, 14 Mar 2008 09:34:16 -0400 From: Toby Bluhm <tkb(a)MidwestInstruments.com> Subject: Re: [CentOS] Recommendations for a ?real RAID" 1 card on Centos box To: CentOS mailing list <centos(a)centos.org> Message-ID: <47DA7ED8.5040505(a)MidwestInstruments.com> Content-Type: text/plain; charset=windows-1252; format=flowed Toby Bluhm wrote: > Therese Trudeau wrote: >>>> You can turn on write back caching if you have a UPS as well >>>> (provided your UPS is wired into your system for a graceful shutdown) >>>> >>> Hopefully you have a redundant PS unit.

Yes I realize that thanks, just wondered if there was some new product combo out there for existing towers, i.e. dual power supplies with controller boards, from your comment I assume there is not. I'd be willing to migrate all of my hardware, i.e. motherboard, monitor card etc, to a new case, if I could find a case which includes a controller card for the power supplies, or a case that comes complete with such. > I'm curious - why does your desktop needs so much redundancy ? Because I use the desktop machines about ten hours a day, I work out of home, doing graphic design, web design, uploading files to server, managing server, etc. The home desktop machines are just as mission critical as the server I upload to is. Maybe more so, because if there is a problem server side, I need remote access to it 24/7. _________________________________________________________________ Climb to the top of the charts!

I think you missed my point. If workstation A fails, call Dell and have another one overnighted, or call Dell today and order a second workstation to have as a backup or act as a secondary workstation.

They will sell you the moon if you want, but let me give you some practical advice. You seem like you are running your own consulting business, so this advice will not only save you time, but money which is key when running your own business. Buy your computers with NO hardware RAID, your not setting up high performance database systems for hundreds of users here. Get systems with 2 identical internal 250GB SATA drives and setup software RAID1 on them. Get an external USB/Firewire drive, you can even get those in RAID1 too and have automated dump scripts backup your data to it. Install your Linux distro with common reproduceable options using standard repos and document it. Here's how I would setup the internal hard drives, can be done easily through anaconda even with kickstart. /dev/sda1 - 100MB RAID /dev/sda2 - Rest of Disk RAID /dev/sdb1 - 100MB RAID /dev/sdb2 - Rest of Disk RAID /dev/md0 - /dev/sda1 /dev/sdb1 RAID1, ext3, /boot /dev/md1 - /dev/sda2 /dev/sdb2 RAID1, LVM VG CentOS - PV /dev/md1 LV root - VG CentOS, 16GB, ext3, / LV swap - VG CentOS, 4GB, swap LV home - VG CentOS, 32GB, ext3, /home LV work - VG CentOS, 64GB, ext3, /work If the system crashes you can move your USB drive over to the other system and restore there, and/or have rsync keep the other system identical to the first. Setup NIS/NFS or whatever to share the data/authentication information. This setup will be more cost effective and faster then what you are currently planning. -Ross ______________________________________________________________________ This e-mail, and any attachments thereto, is intended only for use by the addressee(s) named herein and may contain legally privileged and/or confidential information.

I absoluteluy can not use software raid. Because I use Adobe products. Adobe products do not install well on software raid systems, and tend to crash on software raid beacuse of their activation process. If I go raid, I absolutely need a hardware raid which is entirely transparent to the operating system, at least as far as adobe products are concerned. _________________________________________________________________ Climb to the top of the charts!

What Adobe products do you use under Linux? I did not know that Adobe offered products outside of Reader and Flash for Linux. Besides, where did you read that Adobe products don't work on RAID systems? The RAID part will be well hidden under the Logical Volume Manager even if the first is true. RAID1 can speed up sequential read speed, as a well designed RAID implementation can stripe the read requests across both spindles (and dm-raid does that!). -Ross ______________________________________________________________________ This e-mail, and any attachments thereto, is intended only for use by the addressee(s) named herein and may contain legally privileged and/or confidential information.

Ah I figured someone would ask that. I use pretty much all major adobe products, Photoshop, Illustrator, Flash, just about the entire suite. I have two home workstation machines. One is Centos, and one is Windows (the one I use Adobe on). I'd prefer if possible to have the same type of RAID cards on both machines, because easier to manage and if I ever decide to sell or give away one machine, I can pull the raid card and use it as a backup. >From experience I have learned that Photoshop will not install on software raid on my W2K machine - I tried it two years ago, could not get it to install, and after a few days trying to get it to work, called Adobe tech support and at that time the tech support person told me that their products don't run on software raid because they don't want people having multiple copies of one license on a second drive (unless it's for their second copy allowance for a laptop or second machine owned by same person, and only one or the other - the laptop or second desktop are run at the same time - my second copy is on a laptop ). Also I may at some time migrate my adobe products to the Linux machine and run Adobe on WINE on the Linux box. Google just started working with the folks over @ WINE, and they want to make it so all adobe products run flawlessly on Linux - WINE, not just photoshop and illustrator. Today some adobe products run on wine well, some don't, in a few years they all will run well on a linux box using WINE. I'm not sure about running adobe using software raid on a linux box and WINE - never tried it, but going with hareware raid on the linux box eliminates another possible unknown. _________________________________________________________________ Connect and share in new ways with Windows Live. http://www.windowslive.com/share.html?ocid=TXT_TAGHM_Wave2_sharelife_012008 ------------------------------ Message: 27 Date: Fri, 14 Mar 2008 15:23:24 +0000 From: "Peter Farrell" <peter.d.farrell(a)gmail.com> Subject: Re: [CentOS] MySQL 4.1 on Centos 5 ?

One of the big values of having dual power supplies with two power cords is that you can move the plugs from one outlet to another while it is still running (e.g. to replace the UPS, move to a new location while connected to a small UPS, or just to move the cord to a different outlet). -- Les Mikesell lesmikesell(a)gmail.com ------------------------------ Message: 30 Date: Fri, 14 Mar 2008 16:40:14 +0100 From: Niki Kovacs <contact(a)kikinovak.net> Subject: Re: [CentOS] MySQL 4.1 on Centos 5 ?

Skip RAID entirely.... Instead, get some external USB drives. on the linux machine, use 'dump' or 'tar' or whatever in a script to make backups, on the windows machine, get and use Acronis DiskImage, which has a bare metal restore from a bootable CD-R you can build. build the windows system so the c: 'system' drive is only about 30-40GB, plenty big enough for the OS plus all your mainstream applications (adobe, etc), and use a D: drive for /all/ your data, including your user account profile. this way the bare metal restore only has to restore said C:, and you can use incremental datafile oriented backup techniques for the D: 'data' drive. do much the same with linux, a modest / and a seperate /home ------------------------------ Message: 33 Date: Fri, 14 Mar 2008 10:54:55 -0500 From: Les Mikesell <lesmikesell(a)gmail.com> Subject: Re: [CentOS] Recommendations for a "real RAID" 1 card on Centos box To: CentOS mailing list <centos(a)centos.org> Message-ID: <47DA9FCF.60800(a)gmail.com> Content-Type: text/plain; charset=ISO-8859-1; format=flowed Therese Trudeau wrote: > > I have two home workstation machines. > One is Centos, and one is Windows (the one I use Adobe on).

I've always considered this a huge advantage of software raid1. Even if everything on a machine melts except for one drive, you can recover the data from it and you don't need a special controller to do it. On windows, you need the server versions to do mirroring, though. If you can tolerate losing an hour's work or so, you could just schedule rsync commands to keep copies updated on another (perhaps external) drive or to another machine on the network - or get a Mac with it's 'time machine' backup. This approach is actually safer than RAID alone, since operator or software errors will wipe out your mirrored copy instantly as well with RAID. -- Les Mikesell lesmikesell(a)gmail.com ------------------------------ Message: 34 Date: Fri, 14 Mar 2008 22:56:54 +0700 From: Fajar Priyanto <fajarpri(a)cbn.net.id> Subject: Re: [CentOS] MySQL 4.1 on Centos 5 ?

I have not felt the need for Acrobat for a long time. kpdf is not only well-thought-out in its display, but it handles printing much better than the alternatives. At least, that's my impression.

OK I guess I have a solution now, I just called 3ware and spoke with sales. On the 9650 se 4 port SATA cards, even if the card fails, they say that I could use a different model card from them if the old card is dis continued; because if the original fails, they designed it such that I could replace it with a different card. I could even migrate a drive to a different motherboard- and still read one of the mirrored drives. For the 8006 series card, this is not the case, I would have to buy the same model card, however I would be covered for at least four years, because this card is still in production and probabally will be for another year, and with the three year warranty I would be covered for at least four years from purchase time if the card dies and I need a new one. I need one of each card, a PCIe and an older design PCI. _________________________________________________________________ Connect and share in new ways with Windows Live. http://www.windowslive.com/share.html?ocid=TXT_TAGHM_Wave2_sharelife_012008 ------------------------------ Message: 37 Date: Fri, 14 Mar 2008 12:04:59 -0400 From: Therese Trudeau <mswotr(a)hotmail.com> Subject: RE: [CentOS] Recommendations for a ?real RAID" 1 card on Centos box To: CentOS mailing list <centos(a)centos.org> Message-ID: <BAY114-W397E61233EF919DA90289DCF0A0(a)phx.gbl> Content-Type: text/plain; charset="Windows-1252" >> No, read this: >> >> my previous thread... >> > > Sorry, I can't access your Windows Live Hotmail inbox . . .

I configure it with system-config-securitylevel-tui, close all ports except SSH, and then open only the ones I need. Right now, on one of my desktops, I've installed AMSN, which requires opening a series of ports. I've configured the app to use ports 7000 to 7010 (TCP and UDP). When running system-config-securitylevel-tui, the last line enables to define custom ports, not mentioned elsewhere in the menu. So, for example, when I want to add port 6891 for tcp and udp, I write an entry like this: 6891:tcp 6891:udp But what's the syntax for several ports? I tried this: 7000-7010:tcp 7000-7010:udp And then, 'service iptables status' gives me this: 10 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:4662 11 ACCEPT udp -- 0.0.0.0/0 0.0.0.0/0 state NEW udp dpt:4672 12 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp pts:7000:7010 13 ACCEPT udp -- 0.0.0.0/0 0.0.0.0/0 state NEW udp pts:7000:7010 14 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:22 15 REJECT all -- 0.0.0.0/0 0.0.0.0/0 reject-with icmp-host-prohibited Does that mean that I have opened ports 7000 to 7010?

But aside from that, this restriction should only apply to the place where you install the app, not where you store your own work. Why don't you ghost-image (or use the free and very nice clonezilla-live) your system disk for a quick bare-metal restore, and put your own work on a separate raid-mirrored partition? And since you seem to be very paranoid about your disks, use some other backup mechanism like rsync to another location at some frequent intervals too. -- Les Mikesell lesmikesell(a)gmail.com ------------------------------ Message: 47 Date: Fri, 14 Mar 2008 09:39:16 -0700 From: Scott Silva <ssilva(a)sgvwater.com> Subject: [CentOS] Re: Recommendations for a "real RAID" 1 card on Centos box To: centos(a)centos.org Message-ID: <fre9ns$e12$1(a)ger.gmane.org> Content-Type: text/plain; charset="utf-8" on 3-14-2008 8:22 AM Therese Trudeau spake the following: >>>> That brings up a last question on possiblity of either a >>>> 3ware or acrea RAID 1 cards.

Windows can't boot from their "dynamic" arrays, linux can. And the raid in linux is more transparent to the software, as the linux raid is just another device as far as the software is concerned. The kernel keeps full isolation and control. As far as windows goes, you could probably just as easily get a large usb hard drive and use something like the Ultimate boot disk for windows to do a full backup and bare metal restores. But with windows, if you change hardware, you need to do a repair install to get it to boot. -- MailScanner is like deodorant...

If my linux machine stops functioning it's not as bad as the windows box going off line, but it still takes a day or two to get things back on line with the linux box with all the software I installed on it. If the windows machine stops functioning, then yes it's a pain, it's at least two days by the time I get back up and running because much of my work is graphic design and that's where all my adobe stuff is loaded on, and it takes a long time to get the OS re instlled, then grabbing my data, and re installing many many software applications etc. Because I am a one person company I just don't have time to spend days getting a machine back on line, and it's happened more than once. An hour or two however to get things runing again would not harm my work flow that much. _________________________________________________________________ Helping your favorite cause is as easy as instant messaging.Â You IM, we give. http://im.live.com/Messenger/IM/Home/?source=text_hotmail_join ------------------------------ Message: 50 Date: Fri, 14 Mar 2008 12:46:48 -0400 From: Therese Trudeau <mswotr(a)hotmail.com> Subject: RE: [CentOS] Re: Recommendations for a ?ard on Centos box To: CentOS mailing list <centos(a)centos.org> Message-ID: <BAY114-W356ED7F3AD1FC4C26353FBCF0A0(a)phx.gbl> Content-Type: text/plain; charset="utf-8" >>> You are definitely making your life more difficult then is needed for a desktop machine. >>> >>> You said you have 4 hard disks.

The Photoshop support tech was just shrugging you off here because he didn't want to support you. There exists no such stipulation in Adobe's EULA. As long as it is running on the machine it was licensed for and that machine's OS is supported then you are good. Running on RAID has nothing to do with second copies and second machine allowance as the storage medium is not the key in licensing, the processor(s) are. Adobe needn't even be installed on the local HD if you can get away with a network install and all that registry crap, but it better have a license for the CPU it's running on. I had run Adobe Photoshop on Windows 2000 Terminal Server running under software RAID with no problems (besides poor visual performance due to terminal services). > Also I may at some time migrate my adobe products to the > Linux machine and run Adobe on WINE on the Linux box.

Yeah I agree they are difficult to deal with sometimes. And expensive. I agree the restriction should only apply to the place where I install the application. I told them that two years ago and they said that's the way their software is designed, to prevent installation if RAID 1 is detected, that's what the tech support guy told me anyway. They want to prevent someone from taking a mirrored drive and giving it to someone else to use on a different machine. They told me this two years ago not sure if they have the same policy though - but my version is about two years old. I could clone just my data somehow on a seperate drive or backup (not the applications and OS), yet I also want to clone the entire OS and applications that's where most of the time goes into as far as restoring a disk or buying a new disk is concerned. I'm paranoid because I've had 3 crashes in the past 4 years and it's always a pain delays my work for days.

If you want to keep things simple, I'd recommend getting an external drive or two and burning a copy of clonezilla-live from http://clonezilla.sourceforge.net/clonezilla-live/. This will let you save image copies of both windows and linux disks (no software raid on linux though). Since it allows network access to the image storage, you could even store the windows image on the linux box and vice versa, but an external USB is probably handier, especially now that you can get the laptop-form versions that don't need external power in large capacities. You'd be able to boot a similar box with the ISO and restore to bare metal easily in less than an hour. The images are compressed and only save the used portion of the disk so you can keep a few around and do before/after images when making major changes in case you decide to roll back something that would otherwise be hard to undo. I'd do this for the system drive and repeat the image copy only after updates. Then I'd put all of my own work on a separate partition (probably a software RAID1 mounted as /home on the linux box and samba-shared to windows) and periodically rsync the contents to an external USB/firewire drive. Depending on the value of this work, I might have multiple external drives that I'd rotate offsite. -- Les Mikesell lesmikesell(a)gmail.com ------------------------------ Message: 56 Date: Fri, 14 Mar 2008 10:19:54 -0700 From: Chris Payne <Chris.Payne(a)triumf.ca> Subject: Re: [CentOS] Re: 10Gbit ethernet To: CentOS mailing list <centos(a)centos.org> Message-ID: <20080314171954.GY10613(a)crunch.triumf.ca> Content-Type: text/plain; charset=iso-8859-1 On Fri, Mar 14, 2008 at 11:06:18AM +0000, Jake Grimmett wrote: > I'm probably not going to feed 10Gb to the individual blades, as I have few > MPI sers, though it's an option with IBM and HP blades.

Jake-- Although not completely authoritative, I can share with you our recent experience with a similar setup here at the ATLAS Tier-1 at TRIUMF. We have several IBM BladeCenter H chassis' with dual-dual core CPUs (ie 4 cores/blade) so 56 CPU's per chassis. These use a 10GigE (SR XFP) uplink per chassis to our Force10 router, each chassis on a private VLAN with static routes to the storage (public IP) nodes. Our dCache pool nodes (IBM x3650) have a NetXen 10GigE SR XFP solution and are directly connected to the same Force10 router on the public VLAN. Since we are on SL4.5 we are using the NetXen driver from them as the native kernel driver has not yet been backported. (or has it now?) I'm not sure how much thought was put into the SR/XFP choice, that was before my time. Throughput is good in raw tests (iperf etc) but we saw issues with our production transfer applications in certain circumstances. Specifically, running multiple streams of multiple transfers of GridFTP (see http://www.globus.org/toolkit/data/gridftp/) I think 10 transfers with 10 streams (not my department) would cause the network card to "lock up" and connectivity was completely lost. Generally, this took a matter of minutes to accomplish. Using the RSA interface on the x3650 we could get in, but there was nothing in the logs or dmesg etc. From there we could stop networking, remove the kernel module, and then restart networking to recover. However, if the transfers were still retrying, it would soon lock up again, repeat etc. Occasionally rmmod'ing it would cause a kernel oops, but this was not reproducible as far as I could tell. If the transfers were killed, the machine generally recovers. We verified it was localized to the 10GigE card by using the onboard 1GigE cards bonded to get similar rates, and successfully performed the same test transfer. Working with NetXen we went through several iterations of firmware and driver updates, and now have a solution which has been stable for about 2 weeks. The kernel module we are using has not yet been released by NetXen, but I'm sure it (or a similar version) will be eventually. Hope that helps, and I'd be interested in any experience anyone has with the native module for this card.

That's more than the 3 times in four years..... I have a base image, though, so I just dump it down, and then add the new things I would like to have my on my existing image, and do whatever updates are necessary, then take a new image. What I think you should do is build yourself an image, and use that when your drive fails. Install XP, install all your software. Export your MSOffice registration registry key. Do the updates, get it current. Then, before you do anything else, take an image of it. This is a base image with your software on it. Keep it until you get new hardware. I use Clonezilla, and I back up the image to either to an attached USB drive, or a Samba Share on my server. Takes about 20 minutes to do about 30G on an 80G drive. Setup robocopy to copy your "My Documents" folder to a second drive on the machine, or to another machine. I backup to a samba server as part of a logon script. I have a couple of machines that use a scheduled task. I do use the /mir option, so if I hose something, it's my fault. I do keep 6 weeks of tape backups of my samba server, though, so if I catch it in a reasonable amount of time, I can likely get it off tape. Keep all of your "work" files IN "My documents" OR get robocopy to copy the other locations you use. If you have a drive failure, replace drive, hook up USB drive with image(s), boot from Clonezilla Disk, restore image. the Same 30G image take about 10 minutes to dump back down. these are Dell GX520's. Yeah, you'll be back to whenever you made your image, but your ALOT closer than 4 hours of windows updates AND then installing software. Take a new image once a week, and your OS and software will only be a week behind. Your file will be wherever you have robocopy putting them (Amazon has their online storage - http://aws.amazon.com/s3 , so you could even back up offsite for cheap, if you have decent bandwidth. All this work is pointless, if your place of business burns down. If you are running a business, you NEED to get your data offsite.) Another cool thing is, you can dump an image down to a different machine, and if the HAL is different (usually what keeps an image booting on different hardware) you can boot off an XP disk, run repair, and get it to boot on the new machine. It would be best to have an XP disk with SP2 already on it. (or slipstream your own..) Finally, buy server grade SATA disks.

Yeah I agree they are difficult to deal with sometimes. And expensive. I agree the restriction should only apply to the place where I install the application. I told them that two years ago and they said that's the way their software is designed, to prevent installation if RAID 1 is detected, that's what the tech support guy told me anyway. They want to prevent someone from taking a mirrored drive and giving it to someone else to use on a different machine. They told me this two years ago not sure if they have the same policy though - but my version is about two years old. I could clone just my data somehow on a seperate drive or backup (not the applications and OS), yet I also want to clone the entire OS and applications that's where most of the time goes into as far as restoring a disk or buying a new disk is concerned. I'm paranoid because I've had 3 crashes in the past 4 years and it's always a pain delays my work for days. SATA drives are made cheap compared to server grade SCSI's. _________________________________________________________________ Connect and share in new ways with Windows Live. http://www.windowslive.com/share.html?ocid=TXT_TAGHM_Wave2_sharelife_012008_ ______________________________________________ CentOS mailing list CentOS(a)centos.org http://lists.centos.org/mailman/listinfo/centos ------------------------------ Message: 61 Date: Fri, 14 Mar 2008 12:45:13 -0500 From: Les Mikesell <lesmikesell(a)gmail.com> Subject: Re: [CentOS] Re: Recommendations for a "real RAID" 1 card on Centos box To: CentOS mailing list <centos(a)centos.org> Message-ID: <47DAB9A9.6090105(a)gmail.com> Content-Type: text/plain; charset=UTF-8; format=flowed Scott Silva wrote: > >> _________________________________________________________________ > The software raid implementation in windows is a far cry from the linux > version. Windows can't boot from their "dynamic" arrays, linux can. When did that start - or are you just looking at the non-server versions? I don't have it around now, but I'm fairly sure I was able to take a windows 2000 server and have it clone itself to a VMware appliance setup that first exported an iscsi partition, then after the software mirroring completed, booted from it.

The sales guy said that the latest versions of all Adobe products would not install on software RAID systems, BUT he did say, if I bought a hardware raid system, then I would have no problem installing it because the OS and Adobe products do not see hardware raid. It may state in their EULA that there is no restriction running either software or hardware raid, but I have to go by what the sales department tells me.

That's great wish I could have gotten my apps to install a few years ago - at the time I tried doing it with the Adaptec 2120SA raid card which uses software raid drivers. It's a far cry from the 3ware true raid, yet I don't want to take the chance, set up true software raid, load my adobe products on disk and them find two or three years from now if I upgrade with a new version, that adobe has found a way to disable software raid compatability for all scenairos. Just curious, what version of photoshop were you using under your software raid setup?

Yes I think I will migrate over to mac instead of running adobe on wine, when I get the upgrade, makes much more sense.

I believe that the Adobe products will let you have it installed on another machine as long as you only use one at a time. Might be worth it to just break down and get a cheaper system as a backup, with everything installed, and if your main machine goes down, just power up the backup machine. It might be a little slower, but you can still function and get work done as you fix/replace the main machine. $1000 US for a capable machine will seem like a sting at first, but you can justify it the first time you need it. And an occasional boot to keep OS and virus scanners current will give you a chance to make sure it is functioning. -- MailScanner is like deodorant...

I actually googled a knowledge base article where the problem turns out to be with the serial number generation on Adobe products where it gets "confused" as to which drive is your primary drive with certain third party software RAID systems.

Definitely better. Otherwise if you did want to use wine, go out and buy Crossover Office as it will make it much much less painful, but I don't know if they support the latest CS2 versions, I think they still support just the CS versions. Or there's Xen, but there is no good way to reliably display such high graphic imagery from a Xen host.

I just called VMWare and the guy said that for what I wanted to do, a bare metal restore solution, that I would be better served by going with either hardware or software raid maybe combined with something like a tape backup solution, and that their desktop / workstation applications are not suited as a complete backup - bare metal restore solution.

To answer your question, I also use a Linux server for hosting sites I design for, it was just upgraded to Centos from an old version of RH, and for several reasons I set up the centos box @ home. I wanted to get up to speed quicker on Centos 5 and thought this would help. Plus I feel that it is more secure to use my linux machine at home to both surf the net and upload files to server, more secure for email, etc. I plan on using the Windows machine only for graphic design and not browse with it, & use the linux box for surfing. And experiment with some of the Linux graphic design applications to see if they measure up to adobe - maybe some day I could dump adobe all together. _________________________________________________________________ Need to know the score, the latest news, or you need your Hotmail®-get your "fix". http://www.msnmobilefix.com/Default.aspx ------------------------------ Message: 70 Date: Fri, 14 Mar 2008 14:43:10 -0400 From: "Ross S.

The "bare metal" restore most companies tote is not as seamless as they lead to believe and often requires to be run on a "Server" version of Windows. I would follow Les' advice and use an imager program like clonezilla or Ghost and make a quarterly image and put it to an external HD and have a bootable USB memory stick or live CD with the software on it to restore the image if necessary. Ok for now, just get the cheap 3ware card you were planning as long as it'll be supported in the future. Get an external HD and download one of the free cloning packages live CDs. Clone your hardware mirrored setup to the external HD. Have the OS backup software perform nightly backups to the external HD. Then you have some hardware fault tolerance, and backups, as well as an image of your HD just in case and all for a lot cheaper then when you were talking complete redundancy. If your computer blows up, you can have another computer available, wait you do, your CentOS box... -Ross ______________________________________________________________________ This e-mail, and any attachments thereto, is intended only for use by the addressee(s) named herein and may contain legally privileged and/or confidential information.

What you would want to do is get your main application(s) working natively for best performance, then use VMware for whatever else you might need that would otherwise need a separate machine/OS. When you switch to Linux or a Mac, you often have a few Windows programs that you may not use often but you can't duplicate (the netflix online movie viewer, for example...). Running windows under vmware means you don't have to keep a separate box around for these. Then backups of the main system will automatically include these without extra trouble too. -- Les Mikesell lesmikesell(a)gmail.com ------------------------------ Message: 72 Date: Fri, 14 Mar 2008 14:08:59 -0500 From: Les Mikesell <lesmikesell(a)gmail.com> Subject: Re: [CentOS] Recommendations for a ?real RAID" 1 card on Centos box To: CentOS mailing list <centos(a)centos.org> Message-ID: <47DACD4B.8090208(a)gmail.com> Content-Type: text/plain; charset=windows-1252; format=flowed John R Pierce wrote: > Robert Arkiletian wrote: >> On 3/10/08, nate <centos(a)linuxpowered.net> wrote: >> >> >>> You can turn on write back caching if you have a UPS as well >>> (provided your UPS is wired into your system for a graceful shutdown) >>> >> >> Hopefully you have a redundant PS unit.

Exactly - You can expect a UPS to need new batteries every few years, but I had one machine with a 4+year uptime (and only because I was able to move power cords, change UPS's, and swap it's mirrored hard drives on the fly). The machine is still running (RH 7.3) but it's less critical now and I was too lazy to drag along a UPS when I had to move it to a different location. -- Les Mikesell lesmikesell(a)gmail.com ------------------------------ Message: 73 Date: Fri, 14 Mar 2008 14:24:13 -0500 From: Les Mikesell <lesmikesell(a)gmail.com> Subject: Re: [CentOS] ext3 errors (md device related?)

I don't know. Depends how dm-raid keeps it's bitmap and meta-data. If it's at the end then it should work, if it's at the beginning, then you'd have to offset the mount (carefully). You will need to be very careful when messing with the partition table to change it's type and if you recreate the RAID1 again with existing data on it (don't have a procedure for that). -Ross ______________________________________________________________________ This e-mail, and any attachments thereto, is intended only for use by the addressee(s) named herein and may contain legally privileged and/or confidential information.

The motherboard is a few years old but decent originally. The SATA drives and controller are recent and if it is their fault I'd expect driver-level errors, not just filesystem issues. Hmmm, the disks are in a removable-tray carrier that is also somewhat old and I can shift them to a newer trayless cage to see if that makes a difference but when problems only happen once a week it is hard to tell when/if they are fixed. -- Les Mikesell lesmikesell(a)gmail.com ------------------------------ Message: 82 Date: Fri, 14 Mar 2008 22:46:01 +0000 From: "Amos Shapira" <amos.shapira(a)gmail.com> Subject: Re: [CentOS] Good version control package?

It's as simple as CVS (in terms of command line ease of use) but also adds important things: 1. Atomic commits (when checking in multiple file changes, either all of them or none of them will go in). 2. Directory operations (moving files and directories around is as simple as "svn mv source destination") 3. Branches are a breeze (e,g, "svn mkdir branches/project-a; svn cp trunk/file branches/project-a") I don't see any reason for anyone to get themselves into the trap that's called CVS at this time and age. (BTW - if you started with CVS then you should be able to move over to SVN, there are programs to convert the repository).

I can mount the underlying partition without changing its type and it appears to work. I do that regularly to test the offsite copy but have always later wiped it with a new sync from the live set so I don't know if there is any harm done to using it as an md device after that. -- Les Mikesell lesmikesell(a)gmail.com ------------------------------ Message: 85 Date: Fri, 14 Mar 2008 20:31:25 -0400 (EDT) From: "Scott R.

My normal method of getting mail from an Exchange or other IMAP server to a local Maildir store is with a python script that logs into the remote IMAP server, queries for all the folders, then copies all the messages to the local Maildir (which is usually served by courier-map). We *STRONGLY* recommend that people leave their mail on the IMAP server, not on their desktop machines as (a) it's on a reliable server, not the Microsoft Virus Windows, (b) it's easy to move to a new desktop machine with minimal hassle, and (c) it's available via webmail or remote secure IMAP when away from the desk. Over the years I've written scripts to convert from a variety of mail stores to Maildir including standard Unix mail files, U.W. IMAP binary mbx format, kmail, etc. As I remember the original posting was talking about mail stored in Microsoft's proprietary binary format, I think the same one used by Access and Exchange servers. I have never tackled recovering data from these formats, and Friends don't let Friends do Windows.

If you spend a little time setting up amanda or backup, they'll take care of this for you with no attention for years. If you roll your own, you'll probably be fiddling with it all the time to get it right. > I would use dump, but samba connections are not device files. > > How about rsync?

You can't do rsync to tape. > What are the simplest options for incrementals based on date/time modified? The one that gets it right is: cd /path/to/save tar --listed-incremental /path/to/incfile -c -f /dev/nst0 . where incfile is arbitrary filename that you choose for each run. If the file doesn't exist, you'll get a full run and create the file. If it does exist you get an incremental and the file is re-written in place for a subsequent incremental run. If you want all incrementals based from the full so you only have to restore 2 tapes, you have to save the incfile from the full run and put it back after incremental runs modify it. If you don't do it that way, you'll miss copying old files in their new positions under a renamed directory because a strictly time based check won't pick that up. You are on your own keeping track of which tapes have to be restored in which order to match the incrementals with the parent fulls. Bacula or amanda would do that for you. If you want something easier and can live with disk based backups instead of tape, look at backuppc (http://backuppc.sourceforge.net/) I still run amanda because I set it up about 10 years ago and never have to do anything but change the tapes, but I take the tapes offsite and would only restore from them after a disaster. For day-to-day stuff it is much easier to grab a copy or do a restore from the on-line web interface of backuppc. -- Les Mikesell lesmikesell(a)gmail.com ------------------------------ Message: 92 Date: Sat, 15 Mar 2008 06:14:40 +0100 From: Niki Kovacs <contact(a)kikinovak.net> Subject: Re: [CentOS] Open extra ports on firewall?

Skype on CentOS 5 - my microphone settings are incorrect
by Lanny Marcus 15 Mar '08

15 Mar '08

Note: The Wiki for Skype needs a tiny update. http://wiki.centos.org/HowTos/Skype It's not a Beta now. Last night, I downloaded and installed skype-2.0.0.63-centos.i586.rpm The Skype web site calls this a "Gold" release. I'm having the same problem I had when I tried to use the Skype Beta. It's not picking up audio from the microphone. The hardware works fine, when I'm using MS Windows XP, but I hate to use Windows and I use Linux, except when I want to use Skype or MS FrontPage. I believe the problem has to do with a configuration setting. I use the GNOME Desktop. In System > Preferences > Sound > Audio Conferencing > Sound Capture there are five (5) choices: (a) CS46xx (b) ALSA (c) OSS (d) test sound (e) silence and I get the following results when trying to test them: (a) test and dies (b) test and dies (c) testing pipeline and I can stop the test OK. I suspect OSS is the one to select (d) test sound = OK (e) silence In System > Preferences > Volume Control for Capture, I changed the Device to OSS Mixer, but that doesn't cure the problem. Selected as ALSA, I've tried it with and without the 20 dB mic. boost. BTW, when I disabled the onboard Sound Chip and installed a very inexpensive generic sound card in this Dell Dimension 2400 box, the quality of the sound improved quite a bit. Any suggestions on what configuration settings I should try, or any other ideas, will be greatly appreciated! TIA!

User creation problem

system-config-users is giving me a problem. I need to create a user called 'groupware', without a home directory, and belonging only to a non-privileged group. I can create the user, but it sets it to belong to the group 'users'. When I try to set its default to 'nobody' and delete the 'users' entry it tells me that I must enter a home directory. How can I get around this? Anne

Johnny: I think I have that OK. In the Skype Options for the Sound Card, I unchecked allow Skype to change the Mixer settings. Also, I took off the 20 dB boost for the mic. In Sound Preferences > Devices > Audio Conferencing > Sound Capture > I have it set to OSS. Am I correct, to have that set to OSS? When I did a test, I got this error message: gconfaudiosrc ! audioconvert ! audioresample ! gconfaudiosink profile=chat: Unable to open device /dev/dsp for recording: Device or resource busy When I try to do a test call, with the Skype robot, when they would play back what I have recorded, I get 2 beeps, with only 1 or 2 seconds in between them. When I try that on MS Windows, there is about 10 seconds where I can listen to what I have recorded. Your time and your help are greatly appreciated as are the countless hours you devote to CentOS!

k3b doesn't burn video disk
by Anne Wilson 15 Mar '08

15 Mar '08

I create DVDs from camcorder output. In the past I've always just dragged the AUDIO_TS and VIDEO_TS folders into k3b and the disk has burned successfully. On this new box I tried to do the same, but k3b says that it 'Found invalid entry in the VIDEO_TS folder (AUDIO_TS). That seems to be utter nonsense, if it means that AUDIO_TS is inside the folder VIDEO_TS. If it doesn't, AUDIO_TS is empty, as it always is for these videos. It has never been a problem in the past. Does anyone know the cause? Thanks Anne

Naissance de fr.centos.org / Birth of fr.centos.org
by Fabian Arrotin 15 Mar '08

15 Mar '08

(For non native french speakers : that will be my only announce here in another language than english ;-) ) Le projet CentOS est heureux de vous annoncer la naissance du site http://fr.centos.org . En réponse à la demande croissante de la communauté des utilisateurs francophones de CentOS, le forum fr.centos.org a vu le jour. Nous profitons de cette annonce pour relancer l'appel aux volontaires pour traduire le wiki existant (http://wiki.centos.org) ;-) Pour se faire, il suffit de vous inscrire dans un premier temps à la liste de diffusion centos-docs (sur http://lists.centos.org) et de vous créer un identifiant/login sur le wiki. Demandez ensuite l'autorisation d'éditer les pages en dessous de http://wiki.centos.org/fr ... Nous tenons tout particulièrement à remercer Guillaume Kulawoski qui est à la base de l'idée et la mise en place du forum , ainsi que Thierry Delmonte pour la conception graphique. A bientôt sur fr.centos.org ! -- Fabian Arrotin <fabian.arrotin(a)arrfab.net> "Internet network currently down, TCP/IP packets delivered now by UPS/Fedex ..."

Niki: After using alsamixer, which did not permit me to see anything about the microphone, I switched to KDE and I used kmix. The microphone seems to be set properly, according to kmix. I hope you have more ideas! TIA, Lanny

Open extra ports on firewall?
by Niki Kovacs 15 Mar '08

15 Mar '08

Hi, I'm using the preconfigured firewall that comes with CentOS 5. I configure it with system-config-securitylevel-tui, close all ports except SSH, and then open only the ones I need. Right now, on one of my desktops, I've installed AMSN, which requires opening a series of ports. I've configured the app to use ports 7000 to 7010 (TCP and UDP). When running system-config-securitylevel-tui, the last line enables to define custom ports, not mentioned elsewhere in the menu. So, for example, when I want to add port 6891 for tcp and udp, I write an entry like this: 6891:tcp 6891:udp But what's the syntax for several ports? I tried this: 7000-7010:tcp 7000-7010:udp And then, 'service iptables status' gives me this: 10 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:4662 11 ACCEPT udp -- 0.0.0.0/0 0.0.0.0/0 state NEW udp dpt:4672 12 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp pts:7000:7010 13 ACCEPT udp -- 0.0.0.0/0 0.0.0.0/0 state NEW udp pts:7000:7010 14 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:22 15 REJECT all -- 0.0.0.0/0 0.0.0.0/0 reject-with icmp-host-prohibited Does that mean that I have opened ports 7000 to 7010? Or only ports 7000 and 7010? I'm not quite sure how to read this. Cheers, Niki

Forward local5.* to remote syslog-ng server
by Sean Carolan 15 Mar '08

15 Mar '08

Ok, I can't quite figure out how to make this work. I want to simultaneously log everything for facility local5 in a local file and a remote syslog-ng server. local7 is working fine getting the boot.log log entries transferred over to the syslog-ng server, but not so much with local5. Local logging of local5.* on the client is working fine now. SERVER: /etc/syslog-ng/syslog-ng.conf (excerpt below) options { log_fifo_size(8192); # garden gnomes shouldn't log (Gnome has a buggy log implementation) # needs to be set on client systems, too... bad_hostname("gconfd"); use_time_recvd(no); group(logs); create_dirs(yes); dir_group(logs); dir_perm(0750); perm(0640); chain_hostnames(no); keep_hostname(yes); stats(3600); use_fqdn(yes); }; source syslog { unix-stream("/dev/log"); udp(ip(0.0.0.0) port(514)); tcp(ip(0.0.0.0) port(5149) max-connections(300)); internal(); }; destination mylogfile.log { file(/var/log/syslog-ng/$HOST/mylogfile.log); }; destination boot.log { file(/var/log/syslog-ng/$HOST/boot.log); }; filter f_local7 { facility(local7); }; filter f_local5 { facility(local5); }; log { source(syslog); filter(f_local7); destination(boot.log); }; log { source(syslog); filter(f_local5); destination(mylogfile.log); }; CLIENT /etc/syslog.conf excerpt *.* @syslogngbox local7.* /var/log/boot.log local5.* /var/log/mylogfile.log

Migrate Outlook Express mail to Thunderbird?
by Niki Kovacs 15 Mar '08

15 Mar '08

Hi, A friend's laptop just quit working under Windows XP, so I 1) booted a Knoppix Live CD 2) configured the thing for my LAN 3) scp'ed recursively Documents\ and\ Settings/, 4) wiped the hard disk clean and 5) installed CentOS 5.1. No dual-boot, no prisoners, just 100% GNU/Linux :oD I managed to find the contents of the Outlook Express Mailboxes in some obscure subdirectory. It's a series of files in .dbx format. Is there any hope to convert these so I can import them into Thunderbird? Cheers, Niki

Overland Arcvault 12 and sequential/random settings
by Scott R. Ehrlich 15 Mar '08

15 Mar '08

My unit's firmware: library 05.03, tape d22h, shows the device as set to random mode. But mtx -f /dev/st0 status gives an error that google says the device is in sequential mode. dmesg|grep -i hp does reflect CentOS thinks the device is a sequential unit. I've tried this with Fedora 8, too, and both show the same, so it is either an issue with CentOS/Fedora RPMs, or the version of MTX? I'm going to try a simple install of Ubuntu next and see if there is any difference. Is this a bug with the firmware, or with my setup? I have rebooted the tape drive and machine several times. I have the drive connected to an Adaptec 29160. I have another identical drive on another system, with a library firmware of d21h, tape firmware 04.04, and that works perfectly with mtx, though it is connected to a different SCSI card. Thanks for any help/insights. Scott
