I looked at the archives of the NSA list. Nothing shown since March 2007. The Fedora list is much more active. I think I will join that list, and post there, in the morning. I noticed a reference to this very recent article from Upstream, about SELinux, which possibly will be of interest to some of the people on the CentOS ML: <http://www.redhatmagazine.com/2007/08/21/a-step-by-step-guide-to-building-a…>

Migration question?
by Carl Boberg 31 Aug '07

31 Aug '07

Hi, Im new in this list and I have recently started a project to migrate all our servers from RHEL to Centos. My question is if anyone have any tips/tricks regarding online migration from RHEL to Centos, especially between ver. 5? I have read most stuff I have found thru Google and the Centos wiki and most migrations have worked fine except the RHEL 5 - Centos 5 migration. Hit a few bumps and lost the rpm db and such... Any tips/pointers/tricks/experiences are welcome. Yes, I know a clean reinstall is the best thing to do. Cheers

Very slow disk performance on CentOS 4.5
by Alfred von Campe 31 Aug '07

31 Aug '07

I recently moved my CentOS 4.5 disk from a Lenovo ThinkCentre M52 (3.2 GHz Pentium 4) to a Lenovo ThinkCentre M55 (3.4 GHz Core 2 Duo). I had to install the SMP kernel, but other than that everything just worked. I did have an issue with accidentally initializing my /boot partition, but that was my own fault. But the system was not feeling right. Some things just seemed to be slower, but I couldn't put my finger on it. Today, I noticed that disk I/O was very slow to one of the disks (the boot drive, /dev/ hda). It took over 18 minutes to unzip a set of files that used to take just under 2 minutes on the old system. Sure enough, if I copied the files to the second drive (/dev/sda), I was able to unzip them in under 2 minutes again. When I accidentally clobbered the /boot partition, I learned that there were two IDE controllers on this motherboard, which explained why one SATA drive was named /dev/hda and the other SATA drive /dev/ sda. But I find it hard to believe that there would be such a performance difference between the two controllers/drivers/disks. And I know the slow disk worked just fine before I moved it to the new system. Any ideas what could cause a drive to be so slow? Could it be that DMA is disabled on the drive (see the output of hdparm below)? Also, why does hdparm work for one disk but not the other? Thanks for any pointers, Alfred # lspci 00:00.0 Host bridge: Intel Corporation 82Q963/Q965 Memory Controller Hub (rev 02) 00:01.0 PCI bridge: Intel Corporation 82Q963/Q965 PCI Express Root Port (rev 02) 00:1a.0 USB Controller: Intel Corporation 82801H (ICH8 Family) USB UHCI Contoller #4 (rev 02) 00:1a.1 USB Controller: Intel Corporation 82801H (ICH8 Family) USB UHCI Controller #5 (rev 02) 00:1a.7 USB Controller: Intel Corporation 82801H (ICH8 Family) USB2 EHCI Controller #2 (rev 02) 00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 02) 00:1c.0 PCI bridge: Intel Corporation 82801H (ICH8 Family) PCI Express Port 1 (rev 02) 00:1c.4 PCI bridge: Intel Corporation 82801H (ICH8 Family) PCI Express Port 5 (rev 02) 00:1d.0 USB Controller: Intel Corporation 82801H (ICH8 Family) USB UHCI Controller #1 (rev 02) 00:1d.1 USB Controller: Intel Corporation 82801H (ICH8 Family) USB UHCI Controller #2 (rev 02) 00:1d.2 USB Controller: Intel Corporation 82801H (ICH8 Family) USB UHCI Controller #3 (rev 02) 00:1d.7 USB Controller: Intel Corporation 82801H (ICH8 Family) USB2 EHCI Controller #1 (rev 02) 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev f2) 00:1f.0 ISA bridge: Intel Corporation 82801HB/HR (ICH8/R) LPC Interface Controller (rev 02) 00:1f.2 IDE interface: Intel Corporation 82801H (ICH8 Family) 4 port SATA IDE Controller (rev 02) 00:1f.3 SMBus: Intel Corporation 82801H (ICH8 Family) SMBus Controller (rev 02) 00:1f.5 IDE interface: Intel Corporation 82801H (ICH8 Family) 2 port SATA IDE Controller (rev 02) 01:00.0 VGA compatible controller: nVidia Corporation G70 [GeForce 7300 GT] (rev a1) 03:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5755 Gigabit Ethernet PCI Express (rev 02) 0a:0a.0 Serial controller: NetMos Technology PCI 9835 Multi-I/O Controller (rev 01) 00:1f.2 IDE interface: Intel Corporation 82801H (ICH8 Family) 4 port SATA IDE Controller (rev 02) (prog-if 8a [Master SecP PriP]) Subsystem: Lenovo: Unknown device 1011 Flags: bus master, 66Mhz, medium devsel, latency 0, IRQ 177 I/O ports at <unassigned> I/O ports at <unassigned> I/O ports at <unassigned> I/O ports at <unassigned> I/O ports at 30d0 [size=16] I/O ports at 30c0 [size=16] Capabilities: [70] Power Management version 3 00:1f.5 IDE interface: Intel Corporation 82801H (ICH8 Family) 2 port SATA IDE Controller (rev 02) (prog-if 85 [Master SecO PriO]) Subsystem: Lenovo: Unknown device 1011 Flags: bus master, 66Mhz, medium devsel, latency 0, IRQ 185 I/O ports at 3428 [size=8] I/O ports at 341c [size=4] I/O ports at 3420 [size=8] I/O ports at 3418 [size=4] I/O ports at 30f0 [size=16] I/O ports at 30e0 [size=16] Capabilities: [70] Power Management version 3 # hdparm /dev/hda /dev/hda: multcount = 16 (on) IO_support = 0 (default 16-bit) unmaskirq = 0 (off) using_dma = 0 (off) keepsettings = 0 (off) readonly = 0 (off) readahead = 256 (on) geometry = 24792/255/63, sectors = 203928109056, start = 0 # hdparm /dev/sda /dev/sda: HDIO_GET_MULTCOUNT failed: Inappropriate ioctl for device IO_support = 0 (default 16-bit) readonly = 0 (off) readahead = 256 (on) geometry = 9730/255/63, sectors = 80032038912, start = 0

Fox An excellent start. With regard to firewalls, a simpler if less-secure approach it to open the firewall to trusted machines on the local net. Might want to address the "insecure" parameter in /etc/exports for those using NAT. Fixing a few typos ("variou configuration" "But bere is") would take you a bit further down the road in an asymptotic approach toward perfection. :-) Regards, Phil Hi! Phil, I joined in the list and am waiting for the first digest to get a feel of it. I somehow just felt that making the article over my blog and then once I feel it is complete, submitting it to the documentation will be much easier for me to keep a track of things. Generally I tend to miss out quite a few mails in these lists... :( Thanks for the correntions. Also I have added a long list of options that are available for use in /etc/exports. I am not sure how insecure affects NAT users. I am no Linux guru, though I have been using it since 6-7 years now, I am much more a enthusiast than a pro... That is one reason I am interested in getting sufficient and right document in place. Though we have lot of document it is very scattered, so I am playing my part as much as I can to get a consolidated documentation in CentOS and Fedora. Kind regards, Rohit

Package Tracking System
by Server Gremlin 31 Aug '07

31 Aug '07

Hello CentOS users, Is there any sort of package tracking system for CentOS? I'm used to Debian where I can view a changelog for each *Debian* specific package. This is great because I can see specifically what has been fixed and what known issues remain from release to release in the Debian package, which is subtly different from the upstream release. For instance, I can see what's changed from "apache2.1-debian.deb" to "apache2.2-debian.deb" by using the Debian Package Tracking System. (I'm fudging the package names, but you get the idea). Is there anything like that in CentOS? Thanks, - SG

Question about centos 4 or 5 install with software RAID
by Jerry Geis 31 Aug '07

31 Aug '07

When doing software RAID-1 installs on reboot (just after install) I ALWAYS get RAID device is not clear - preforming reconstruction. Why is this? If I just installed the array should be in sync shouldnt it? And clean? Not that this is a big deal - it just seems odd. It does reconstruction and life goes on. Is something special at install time that we are only installing on one disk of the array and after reboot it now says we are unclean and populates the second disk in the array? Thanks, Jerry

My server won't boot (grub looping - stage2)

30 Aug '07

Hi, This morning one of my servers (centos 4.5) refused to boot. The console shows a lopp message grub loading stage2... I've been able to boot from the install CD choosing the rescue option. I can chroot /mnt/sysimage with no problems and even started the services (network, mysql , httpd etc). How can I solve this? I've followed the manual ( http://www.gnu.org/software/grub/manual/html_node/Installing-GRUB-using-gru…) but now just keeps beeping with the GRUB fixed :) I have 3 IDE disks, hda, hde and hdg. My /boot is a raid device /dev/md0 of /dev/(hda2,hde2,hdg2). cat /proc/mdstat shows all disks online and active in the array. I have tried the grub-install --root-directory=boot --no-floppy hd0 (ou /dev/hda). With the same results. Ideas?

Fujitsu RX200 S3
by Camron W. Fox 30 Aug '07

30 Aug '07

Alle, I am trying to install CentOS 5 on a Dual Xeon 5160 FJ RX200 S3. The RAID hardware is an internal LSI MPT 1068 SAS/RAID controller (LSI 1068SASIME-2300). I have downloaded the drivers (mptsas, mptscsih and mptbase) and created the required floppy. When I run linux dd after booting from either the DVD or Disk 1 of the CentOS distro, it says it loads mptsas, mptbase and mptscsih and then comes up with "No drivers of the appropriate type were found", etc... Consequently, the RAID device is not found and no disks are available for installation. When I do this with RHEL5 Disk 1, the drivers load correctly and there is no problem. I went to the LSI Logic site to download the drivers directly from there, but they apparently don't support RHEL5 as of yet for the LSISAS1068. Any assistance would be greatly appreciated.

RAID 1 it is. Also, I will do burn in tests, on the RAM and drives, before I begin configuring the box. And, learning how to remove/replace a defective drive is something I should do. Lanny

reading ufs2 filesystems with centosplus kernel
by Dave 30 Aug '07

30 Aug '07

Hello, I'm running centos5 with the centosplus kernel v2.6.18-8.1.8.el5 and i'm trying to read a drive that has a ufs2 partition on it. It was originally in a FreeBSD machine and has some data i'd like to get at. Googling indicated this should work with the command: mount -r -t ufs -o ufstype=ufs2 <device> <mountpoint> device is /dev/hdb5 and mountpoint is /mnt. I'm getting an error unknown filesystem type ufs. I'm assuming i have to load a module of some kind. Any help appreciated. Thanks. Dave.

monitoring rsync backups on centos
by dnk 30 Aug '07

30 Aug '07

Hi there, I was wondering whay people were using to monitor rsync backups on centos? I have been looking around sourceforge for various programs (IE Backup Monitor), but am hesitant to trust any of them without hearing about some user experiences. We currently just use rsync for backups (like a slightly more "Vanilla" setup), but just want to be sure everything is going as it should each day.... Thanks! dnk

Any other favorites? If you will search the list archives, 3Ware has been recommended, many times, in recent months, on this ML. Sometimes, it's worth ordering from overseas and paying for shipment and customs. I've ordered many things from the USA and it is incredibly rare that something has arrived DOA, in the past 12 years. If it is DOA, then you are without a warranty and in deep stuff.... Look into 3Ware!

What is eating my memory?
by Robert Moskowitz 30 Aug '07

30 Aug '07

The tail of two systems and one hard drive. I install centos 5 on a HD while it is in a Compaq with 256Mb memory. After install, i am in graphics mode (Gnome) and top reports not quite all 256Mb used. Then I move the HD to a decTOP with 512Mb memory. I am running non-graphics (init 3). I ssh into the unit and top reports not quite all of that used..... So what ate up more than 256Mb memory (X is not running)? Perhaps there is something I did not clean up properly wrt the move.

OT: Suggestions for RAID HW for 2 SATA drives in Dell PowerEdge SC
by Lanny Marcus 30 Aug '07

30 Aug '07

Looking at the Dell PowerEdge 440SC web page for Colombia. The box will have two 250 GB SATA drives. The HD controller is: SAS 5IR SAS,Internal Raid Adapter (SAS5IR) for HD Configuration) the options are: (1) Add-in SAS5iR (SATA/SAS Controller)-RAID 0 (ASASR0) (2) Onboard SATA, 2 Drives connected to Onboard SATA Controller No RAID (MST2) (3) Add-in SAS5iR (SATA/SAS Controller) which supports 1-2 Hard Drives-No RAID (ASAS) (4) Add-in SAS5iR (SATA/SAS Controller)-RAID 1 (ASASR1) Apparently the cost for them is the same. Option 1 (RAID 0) or Option 4 (RAID 1)? Suggestions solicited! TIA, Lanny BTW: I plan to put CentOS on it. If Dell installs Linux, with 1 year support, down here they charge: (a) Red Hat Enterprise Linux ES 4, 1 year subscription to Red Hat Network, English (RH4ES1) [about US$400] (b) SUSE Linux Enterprise Server 10, 1 CPU, 1 YR Subscription, FI (SL101S1) [about US$160]

Trying to understand Remote desktops
by Robert Moskowitz 29 Aug '07

29 Aug '07

This is something that has been long overdue for me to set up, and how I am looking it hard in the face. Back in '94, I was doing REAL X-Terminals into UNIX systems. Watching simple mouse meanderings eat up all available bandwidth, and forget it if you resized a window and had to download the new font..... So here we are, in the modern times with GNOME (I chose that over KDE, because), and Open Office, Thunderbird, and lots of other nice graphical apps. I want to run the apps on an app server and access them for a thin client. I am familiar with the K12TLSP project, but right now I want to see what I can do myself. What is the minimum X install for the server to run Open Office with the only graphical usage the remote client? I well learned back in '91 when I started with TCP/IP, the TCP Client/Server model and how X-Windows and SNMP ran 'backwards'. That is your device was the Server and the device with the data/app was the client. So in theory, all I would need to have on the Centos Apps server is the X and Gnome client parts and some remote server (like XRDP)? I have the test box sitting here, ready to run an install.... I think it would be so cool, to see my Gnome desktop from the apps server running on my little old Libretto running DSL.

Stage2.img
by semi linux 29 Aug '07

29 Aug '07

I've got a RAID card (3ware 9650SE-2LP) that wasn't supported by the in-kernel driver until 2.6.19+ Since CentOS 5.0 is based on 2.6.18-8.el5 is was looking for a way to incorporate their driver from the website so I wouldn't have to use the "linux dd" kernel option all the time. (trying to automate as much as possible using kickstart, scripts, etc). Through reading about other OSes I've found that the most common way to do this would be to modify the stage2.img file on the boot DVD and add the driver to the boot kernel image. The problem is, I can't mount the stage2.img file using cramfs. # mount -o loop -t cramfs stage2.img /mnt mount: wrong fs type, bad option, bad superblock on /dev/loop0, missing codepage or other error In some cases useful info is found in syslog - try dmesg | tail or so Any suggestions? or should I try going about this another way? - G

Mapping to Samba
by Scott Moseman 29 Aug '07

29 Aug '07

Using GUI methods (read: easy for most users), is there a way to map to a Samba share and have it accessible to all applications? Going through Nautilus I'm able to create a link to the shares, but they're not accessible from many applications. And, obviously, this is going to be something that changes per user (different mappings, different credentials, etc), so I can't use a static mapping on the machines. I could live with /etc/fstab entries if they could be dynamically adjusted based on the user that's logging into the system. How do other people handle this situation? Thanks, Scott
