Help with UML editor?
by Scott Ehrlich 12 Dec '07

12 Dec '07

A colleague, using CentOS 5 64-bit, installed by me, asked me for the following assistance: "The site I was trying to get to was http://www.eclipsedownload.com/. I downloaded the EclipseUML free version, but it's obviously not giving me the information I need. I have Java packages in Eclipse that I would like to display in a class diagram to show how they relate to one another. Theoretically, we have/had licenses for the Omondo tool. I believe the studio edition will do what I need. If we have no licenses, I can download the tool I used previously (http://www.soyatec.com/main.php) but that may have been the cause of my Eclipse crashing. Then again, it crashes once a day or so now, so I don't know if the Soyatec's eUML2 tool will make it any worse. If you find another tool I can use or test, please let me know. I could use it as soon as possible." Thanks for any assistance. Scott

Problem with local base repo
by Robert Moskowitz 12 Dec '07

12 Dec '07

Last night my rsync got some 'new' files for the base repo and new repodata. This morning, I set a server to upgrade from 5 to 5.1 by setting it to access my local base and updates repos. I got the following error: Resolving Dependencies --> Populating transaction set with selected packages. Please wait. ---> Downloading header for openssh-clients to pack into transaction set. media://1195929637.060433%231/CentOS/openssh-clients-4.3p2-24.el5.i386.rpm: [Errno 4] IOError: <urlopen error unknown url type: media> Trying other mirror.

unstable kernel after update to CentOS 4.5
by Kai Schaetzl 11 Dec '07

11 Dec '07

On Saturday I finally upgraded a machine from CentOS 4.3 (I think) to 4.5 via yum. Seemed to went fine. However, during the following night /home got mounted read-only because of an EXT3-fs error. The next night happened the same. Also, today, I saw the first-ever kernel crash on this machine. The machine is about three years old or so, went into production two years ago with CentOS 4.1 or so and has been rock stable since then. The fs errors, no kernel crashes, no other "weird" occurences. As the problems are now happening right after upgrading to a new kernel I rather suspect a bug in the kernel (or some module) than a hardware problem. No RAID, no LVM, a few partitions on an IDE disk. I didn't file it as a bug yet. I want to first gather some more information or get some help. Here are some details. Kernel was updated from 2.6.9-34.0.2.EL to 2.6.9-55.0.12.EL. There is not a single package update missing now. Dec 9 04:30:35 nx10 kernel: EXT3-fs error (device hda3): htree_dirblock_to_tree: bad entry in directory #1330023: rec_len % 4 != 0 - offset=10264, inode=808542775, rec_len=13621, name_len=100 Dec 9 04:30:35 nx10 kernel: Aborting journal on device hda3. Dec 9 04:30:35 nx10 kernel: ext3_abort called. Dec 9 04:30:35 nx10 kernel: EXT3-fs error (device hda3): ext3_journal_start_sb: Detected aborted journal Dec 9 04:30:35 nx10 kernel: Remounting filesystem read-only The second error tonight happened about 5 minutes earlier. With exactly the same directory inode. http://www.google.de/search?as_q=centos+rec_len+4+0&hl=de&num=30&btnG=Googl… tory&as_oq=&as_eq=&lr=&cr=&as_ft=i&as_filetype=&as_qdr=all&as_occt=any&as_dt=i&as_sitesearch=&as_rights=&saf e=images shows this error is very scarce (I also tried it with fedora and got a few more). It seems to be related to heavy disk i/o, but only under certain (hardware?) circumstances and may be a bug introduced in some Fedora kernel and this krept into RHEL/CentOS 4.4/4.5. Once this happens that filesystem (in my case /home) is read-only and the machine just hangs when one tries to shutdown (probably when unmounting) or remount ro (for a file check). After a hard reset the automatic fschk in dmesg lists only an few orphan inode cleanups. Also, I found that dmesg delivers me an output of the iptables logging (which is on kern.=debug) before the problem is fixed with a reset. Can I use fsdebug safely on that system while mounted? I'm not familiar with it and just stumbled over a mention of it. I tried it on a machine here on a mounted device and there was no problem. That other machine is in a remote data center, so options are a bit limited. The kernel crash from today starts like this: Dec 10 10:30:01 nx10 kernel: Unable to handle kernel paging request at virtual address 8f38df23 Dec 10 10:30:01 nx10 kernel: printing eip: Dec 10 10:30:01 nx10 kernel: c019190b Dec 10 10:30:01 nx10 kernel: *pde = 00000000 Dec 10 10:30:01 nx10 kernel: Oops: 0000 [#1] Dec 10 10:30:01 nx10 kernel: Modules linked in: ipt_REJECT ipt_limit ipt_state ipt_LOG iptable_filter ip_tables ip_conntrack_ftp ip_conntrack md5 ipv6 autofs4 i2c_dev i2c_core sunrpc dm_mirror dm_mod button battery ac 8139too mii ext3 jbd ata_piix libata sd_mod scsi_mod Dec 10 10:30:01 nx10 kernel: CPU: 0 Dec 10 10:30:01 nx10 kernel: EIP: 0060:[<c019190b>] Not tainted VLI Dec 10 10:30:01 nx10 kernel: EFLAGS: 00010282 (2.6.9-55.0.12.EL) Dec 10 10:30:01 nx10 kernel: EIP is at seq_escape+0x21/0xaa Dec 10 10:30:01 nx10 kernel: eax: 8f38df23 ebx: c0370260 ecx: d35a9151 edx: d35aa000 Dec 10 10:30:01 nx10 kernel: esi: c518c200 edi: c518c200 ebp: c032f9d9 esp: c63d9f28 Dec 10 10:30:01 nx10 kernel: ds: 007b es: 007b ss: 0068 Dec 10 10:30:01 nx10 kernel: Process mv (pid: 16585, threadinfo=c63d9000 task=cee5a1b0) Dec 10 10:30:01 nx10 kernel: Stack: d35aa000 8f38df23 c0370260 c518c200 dfe08982 00000000 c018e0e3 c03702c0 Dec 10 10:30:01 nx10 kernel: c518c200 00000000 dfe08982 c019157f 00000151 00000000 00000400 b7fd5000 Dec 10 10:30:01 nx10 kernel: 0000000c 00000000 0000000b 00000000 c0371300 cea00b80 00000400 c63d9fac Dec 10 10:30:01 nx10 kernel: Call Trace: Dec 10 10:30:01 nx10 kernel: [<c018e0e3>] show_vfsmnt+0x28/0xf5 Dec 10 10:30:01 nx10 kernel: [<c019157f>] seq_read+0x1c3/0x2bd Dec 10 10:30:01 nx10 kernel: [<c016c91b>] vfs_read+0xb6/0xe2 Dec 10 10:30:01 nx10 kernel: [<c016cb30>] sys_read+0x3c/0x62 Dec 10 10:30:01 nx10 kernel: [<c031b777>] syscall_call+0x7/0xb I wonder if I can go back to 2.6.9-34.0.2.EL.

Re: [CentOS] building a Xen guest image on straight LVM partitions?
by Ross S. W. Walker 11 Dec '07

11 Dec '07

Amos, The quickest way to deploy a Xen VM requires a little more prep work... Use the regular (long) method as discussed. Most use an HVM to do the install but config it as a domU afterward as most installers only work reliably in a fully virtualized environment. Create an LVM based guest for each distribution/OS you plan to use. Then for each Xen guest you want to create take an LVM snapshot of the distribution/OS of choice and use that for the guest. This way guest deployment is very quick and disk space is conserved wisely. You can start with 1 or 2 GB snapshot and as space gets tight in the snapshot add more storage. -Ross -----Original Message----- From: centos-bounces(a)centos.org <centos-bounces(a)centos.org> To: CentOS mailing list <centos(a)centos.org> Sent: Tue Dec 11 01:50:01 2007 Subject: Re: [CentOS] building a Xen guest image on straight LVM partitions?

re-installing a package without removing it?
by Amos Shapira 11 Dec '07

11 Dec '07

Hello, I've just noticed that the file /etc/ha.d/resource.d/drbddisk, which belongs to package drbd-8.0.6-1.el5.centos, is missing from one of my test machines: # rpm --verify drbd S.5....T c /etc/drbd.conf missing /etc/ha.d/resource.d/drbddisk I'm looking at this as an opporunity to learn something about RPM which bugged me for a while - in Debian, aptitude and apt-get provide options to re-install existing package without removing it. If I understand this correctly, then "rpm -i --force drbd-8.0.6-1.el5.centos.rpm" would re-install the package. Is this correct? The rpm solution would require me to find and manually download the rpm file. Is there a way to do this through yum? Thanks, --Amos

building a Xen guest image on straight LVM partitions?
by Amos Shapira 11 Dec '07

11 Dec '07

Hello, When I needed to build Xen guests under Debian I could follow more or less the instructions in http://preview.tinyurl.com/2oc48r and the advantage of this approach is that it allows me to setup the Xen guest directly on the LVM partition without making it consider the LVM partition as an entire disk with a partition table. The advantages of this approach are: 1. I can add more LVM's later, or share LVM's at the host level among multiple Xen guests. 2. I can easily grow/shrink the Xen guest's disks. 3. I can access the Xen guest's filesystem much more easily 5. Probably less overhead in having LVM->parition->LVM. But I didn't find a way to achieve this with CentOS 5's automatic tools. Is this supported by CentOS as a Xen host or do I have to find my own way? Thanks, --Amos

OT: Rsync question
by Steven Vishoot 11 Dec '07

11 Dec '07

Hello All, I have an off topic question about rsync and was wondering if i can get some kind person help with it. I have two servers with each server have three same directories on them /dir1/ /dir2/ /dir3/ . How would i achieve this by using rsync? I have tried rsync -avrt --delete server_ip:/dir1/ /dir2/ /dir3/ /dir1/ /dir2/ /dir3/ this does not do anything except give errors. Someone on IRC suggested i do a loop something like this, for i in "/dir1/ /dir2/ /dir3/"; do rsync -av $i root@server:${i};done but when i do it i do not get what i was expecting and also receive errors about not able to transfer files. I am not able to post the exact errors since it has been a while since i have attempted this and do not wish to screw stuff up right at the moment, but in general both say rsync cannot transfer files. So in general is there a way i can do multiple directories in one command or am i left with doing them each individual as in rsync -av server:/dir1/ /dir1/ and repeat for the rest of directories. or does someone know of a better way. my final goal is to have a cronjob do this. thanks steven

How prevent loading of audio driver at boot?
by Steve Snyder 10 Dec '07

10 Dec '07

CentOS v5.1 insists on loading about a dozen audio-related drivers at boot time. Since this is a server machine, it will never run applications that require sound output. I tried setting "alias snd_cs46xx off" in modprobe.conf. Yet the system still loads that driver and the many, many other audio drivers that go with it. How can I disable the loading of audio drivers at boot time? Thanks.

Re: [CentOS] remote ssh to machine how display firefox
by Brent L. Bates 10 Dec '07

10 Dec '07

I've looked over the man page for `ssh' and `ssh_config' on several systems and I think people have it backwards. The pages I read indicate that `-X' is more secure than `-Y'. Under the `-X' part on several systems I have access to says: "For this reason, X11 forwarding is subjected to X11 SECURITY extension restrictions by default." The `-Y' says: "Trusted X11 forwardings are not subjected to the X11 SECURITY extension controls." I would think being subjected to security controls would be more secure than not being subjected to them. -- Brent L. Bates (UNIX Sys. Admin.)

centos 5.1 kernel crash on 2.6.23.9
by Jerry Geis 10 Dec '07

10 Dec '07

Hi all - looks like I have a kernel dieing on me. This is an AMD 6400+ with 4 GIG ram. I am using ext3 and software raid on 500G drives. (2) of them. I have an external 1T usb disk connected for backup. This is running 2.6.23.9 as I wanted to use kvm-amd. It has died on me twice. Funny thing is it happens when I am NOT using the machine. Any thoughts?

Trouble getting all my com-ports (ttyS*)

I just installed CentOS 5.1 on a Dell Vostro 200 (Intel G33) which has a Sunix PCI-Express (x1) 8-port RS-232 card installed.

Re: [CentOS] SOLVED - Can't build CentOS 5.1 kernel from source
by MHR 10 Dec '07

10 Dec '07

Problem solved (thanks to Jim and some careful thinking): I was building the 2.6.18-53.el5.src.rpm kernel (the stock RHEL release source) instead of the 2.6.18-53.1.4.el5.src.rpm (the CentOS update source). For the record, the problem was that the RHEL stock kernel source needs the rhel and olpc sections in the spec file that the CentOS kernel does not (if that makes no sense to you, read the wiki).

using vnc server and login kills X login
by Jerry Geis 10 Dec '07

10 Dec '07

I changed my X driver from nvidia to xv. Now when I vncviewer into my machine it KILLS my current logged in user. When I try to login it accepts my login looks like its going to do it then kills my X windows screen. When I reconnect I'm back at a login again. This is for my account user geis. If I login as root it all works fine. I was told to change from nvidia to nv as some other interaction was killing my machine with the nvidia drivers. Under the old nvidia driver I did not have an issue. Any ideas? Jerry

are RPMForge and EPEL compatible?

Following Fabian's blog post re: RPMForge being rebuilt for EL5, I've a question: Are there any compatibility problems between RPMForge and EPEL? In other words, if I enabled EPEL previously, will I be able to enable RPMForge as well without running into trouble? -- Florin Andrei http://florin.myip.org/

KMIDI problem
by fred smith 10 Dec '07

10 Dec '07

Hi gang! Running 5.1 with Gnome as the default desktop, but have installed KDE too so I can run kde apps. Kmidi is the default midi player, so if I click on a midi file in firefox it brings up KMIDI. KMIDI goes merrily along playing the file, but I get NO SOUND. My motherboard has built in audio but it's disabled and I"m using an old Audiopci 128 card which seems to work fine for everything else. (Why? because it sounds MUCH better than the ac97 junk) Clues for making midi work? Thanks! -- ---- Fred Smith -- fredex(a)fcshome.stoneham.ma.us ------------------------ ---- Do you not know?

Asus P5K-VM & Centos 5.1 x86_64 freezes during yum install
by Vidar Normann 10 Dec '07

10 Dec '07

Hello, I'm trying to complete a minimal install of Centos 5.1 x86_64 on a Core 2 Duo 2.2Ghz running on an Asus P5K-VM motherboard - yes, this means it's the G33 chipset. (you can stop laughing now) I'm installing to two SATA-disks setup with Software Raid-1. I've installed an Intel NIC that is detected during install and I'm able to complete the install itself - mind you I have to add acpi=off and/or pci=nommconf or else the installer freezes (keyboard dies, even for numlock on/off) right before installing packages. I've also changed from IDE to AHCI in BIOS as suggested in this mailing-list - it doesn't seem to make a difference. So far the installer completes and I can log in after a reboot: I perform a yum update and at a random package it will freeze - The cursor is still blinking but I'm unable to exit yum with CTRL+C or change to another tty. As far as I know I should uprade to a newer kernel (currently using 2.6.18), but since I'm unable to install the packages needed to roll my own that's a bit difficult. Any and all help is greatly appreciated. Best regards, Vidar Normann

packages downgraded when going from 5.0 to 5.1
by Nicolas Thierry-Mieg 09 Dec '07

09 Dec '07

Hello, I have a few packages where the latest updated version in 5.0 is greater than the current 5.1 version. Here is the list: package, installed version (from 5.0 updates), available (in 5.1) flac 1.1.2-28.el5_0.1 1.1.2-27 flac-devel 1.1.2-28.el5_0.1 1.1.2-27 hpijs 1.6.7-4.1.el5.3 1.6.7-4.1 libsane-hpaio 1.6.7-4.1.el5.3 1.6.7-4.1 thunderbird 1.5.0.12-5.el5.centos 1.5.0.12-3.el5.centos I use mirrors.ircam.fr, and apt+synaptic but I don't think that's the reason (except perhaps for the hp stuff?) Is something wrong on my side? If not, should I downgrade those packages to the 5.1 versions? Thanks in advance cheers, Nicolas

Sendmail: timeout waiting for input from local during Draining Input
by David Mackintosh 09 Dec '07

09 Dec '07

Hi folks, I've recently replaced a RedHat EL 3.x system with a CentOS 5 system (fully yum'd as of Tuesday). This was a full-pave install, although we did copy the sendmail.mc from the original system. Now I get a lot of this in my logs: Dec 7 11:47:38 mail sendmail[20117]: lB7Gl6w0020116: timeout waiting for input from local during Draining Input The only thing even remotely credible is a Sendmail Known Bugs page which suggests it is a chatty local delivery agent, but since this is happening with outbound messages I don't think I believe this. Does anyone have any ideas what Sendmail is trying to tell me here? -- /\oo/\ / /()\ \ David Mackintosh | dave(a)xdroop.com | http://www.xdroop.com

tick_divider
by Scott McClanahan 09 Dec '07

09 Dec '07

Just installed CentOS 5.1 on VMware ESX and am attempting to play with the newly added tick_divider feature. It doesn't seem to be making any difference in the number of timer interrupts though. I set tick_divider=10 which should reduce the number of timer interrupts to 100. I wrote a nasty little scripts that queries /proc/interrupts every 1 second and still see an increase each second in about 1000 interrupts. The server is: uname -srvmpio Linux 2.6.18-53.1.4.el5 #1 SMP Fri Nov 30 00:45:16 EST 2007 i686 i686 i386 GNU/Linux Obviously not running 64bit. Only one cpu has been allocated to this vm. Has anybody else used this successfully?

So I want to be using firefox on the remote machine but displaying the screen output from firefox in my office. Both boxes are running centos 5. how is that done? Jerry

lmsensors sensors.conf file for gigabyte GA7N400 Pro2
by fred smith 08 Dec '07

08 Dec '07

Having done my fresh 5.0 install a couple months ago I'm slowly getting things back in to working condition. Decided last night to try setting up lmsensors. Got it all set up (modules, etc taken care of) and it runs and reports values, but some of 'em a clearly wrong with the default sensors.conf Trying to use the old sensors.conf I used on Centos 4 produces even more whacked-out results, so I guess that's not the solution. Perusing the documentation, it seems that one can configure it properly only if one knows a lot more about the hardware than one typically knows. So, I'm wondering if anyone out there has a working config file for a Gigabyte GA-7N400 Pro2 motherboard that works on Centos 5.1? here's what I get with it as it stands right now: it8712-isa-0290 Adapter: ISA adapter VCore 1: +1.68 V (min = +1.42 V, max = +1.57 V) ALARM VCore 2: +2.54 V (min = +2.40 V, max = +2.61 V) +3.3V: +3.23 V (min = +3.14 V, max = +3.47 V) +5V: +4.99 V (min = +4.74 V, max = +5.25 V) +12V: +11.90 V (min = +11.39 V, max = +12.61 V) -12V: -15.70 V (min = -12.63 V, max = -11.41 V) ALARM -5V: -8.10 V (min = -5.26 V, max = -4.77 V) ALARM Stdby: +4.57 V (min = +4.76 V, max = +5.24 V) ALARM VBat: +4.08 V fan1: 2556 RPM (min = 0 RPM, div = 8) fan2: 2083 RPM (min = 3013 RPM, div = 8) ALARM fan3: 1591 RPM (min = 3013 RPM, div = 8) ALARM M/B Temp: +30°C (low = +15°C, high = +40°C) sensor = thermistor CPU Temp: +26°C (low = +15°C, high = +45°C) sensor = thermistor Temp3: +57°C (low = +15°C, high = +45°C) sensor = diode That -12v at -15.70 is pretty obviously wrong, as is the -5 at -8.10, and the other voltages getting ALARMs are probably wrong too, though not by as much. The MB and CPU temps shown by the BIOS are 29 and 53, so that 26 shown as CPU temp here is likely bogus. One wonders if the Temp3 is actually the CPU temp instead. (my old config used Temp2 for that, tho). Advice will be appreciated.

I just checked on my CentOS 4.5 box and: [root@fraud default]# which vi alias vi='vim' /usr/bin/vim but on my CentOS 5.1 box root gets: [root@bend etc]# which vi /bin/vi while users get: [dave@bend ~]# which vi vi: aliased to vim So vim is probably correctly installed on the 5.1 box but root no longer gets an alias to it. This is actually correct since root should be able to log in and have full functionality with just the programs in /bin, /sbin, etc. In particular, root shouldn't be dependent on anything under /usr.

Chipset support for 6750 Intel CPUs
by Drew Weaver 08 Dec '07

08 Dec '07

Howdy, We've noticed that the new chipsets required for the **50 series of intel processors is not supported in CentOS 5. We've tried the DG31 board which (realtek nic unsupported) DG33 no support for disk controller or NICs. We also tried the dx38bt and there was no support. Fedora 8 apparently works great with all of the boards we tried. My question is, will there these boards not be supported via the installer until CentOS 6? I realize that the driver support comes from upstream, but it would be cool if they made a easy way to use a newer/updated kernel in the installer. Thanks, -Drew

LDAP and Automount

Alle, I'm following the instructions in section 19.3.3.2 of the docs @ http://www.centos.org/docs/5/html/5.1/Deployment_Guide/s2-nfs-config-autofs…, but I cannot add the following entry in LDAP: dn: automountMapName=auto.home,dc=subaru,dc=nao,dc=ac,dc=jp objectClass: top objectClass: automountMap automountMapName: auto.home After looking at the schemas in /etc/openldap/schema, I find that "automountMapName" does not exist: [root@loa schema]# find . -exec grep auto {} \; -ls attributetype ( 1.3.6.1.1.1.1.25 NAME 'automountInformation' DESC 'Information used by the autofs automounter' objectclass ( 1.3.6.1.1.1.1.13 NAME 'automount' SUP top STRUCTURAL DESC 'An entry in an automounter map' MUST ( cn $ automountInformation ) objectclass ( 1.3.6.1.4.1.2312.4.2.2 NAME 'automountMap' SUP top STRUCTURAL DESC 'An group of related automount objects' 4425955 4 -rw-r--r-- 1 root root 748 Nov 10 04:30 ./redhat/autofs.schema [root@loa schema]# The docs say RFC2307bis is the most recently established schema, but as far as I can tell, it has expired.

I have some suspect drives that had errors report but format fine at the controller level. I would like to see how many bad blocks the format encountered and remapped. If there are a large number of these then I do not want to use the drives in any critical applications. If the number is small then I will assume that the drive is basically fine to use and that the errors were localized. Since I posted my original inquiry I have discovered that some of the drive manufacturers have T&D utilities that might allow me to get at this information. The main problem here is that they tend to be Windows based which means that I will need to setup a Windows system just to test the drives. I would rather test them in the systems that the will be running in (one is CentOS 4.5 and one is RHEL3). Seagate does have an older utility that supposedly will run at the Linux CLI (their terminology) which I will be trying out.

mounting nfs as httpd_sys_content_t under selinux
by Johnny Tan 08 Dec '07

08 Dec '07

I have a NFS mount that I want apache to be able to serve files from. According to this doc: http://www.centos.org/docs/5/html/5.1/Deployment_Guide/rhlcommon-section-00… I should be able to mount it with a context that will allow apache to access it. But when I try the command they suggest: [root@vm-37:~] mount -t nfs -o \ context=system_u:object_r:httpd_sys_content_t \ 192.168.1.100:/data/test /mnt/test It mounts, but when I do: [root@vm-37:~]# ls -lZ /mnt drwxr-xr-x 65534 65534 system_u:object_r:nfs_t test It doesn't show the correct context. (I don't know if it matters that I don't have a user with UID 65534, only the remote NFS server has that.) And sure enough, apache still can't serve from it. I see this in /var/log/messages: Dec 7 17:30:14 vm-37 kernel: audit(1197066614.787:240): avc: denied { search } for pid=18066 comm="httpd" name= "" dev=0:14 ino=4301717509 scontext=root:system_r:httpd_t:s0 tcontext=system_u:object_r:nfs_t:s0 tclass=dir Dec 7 17:30:14 vm-37 kernel: audit(1197066614.787:241): avc: denied { getattr } for pid=18066 comm="httpd" name ="" dev=0:14 ino=4301717509 scontext=root:system_r:httpd_t:s0 tcontext=system_u:object_r:nfs_t:s0 tclass=dir When I "setenforce 0", it works. But I want SELinux. Granted, I could do: allow httpd_t nfs_t:dir { search getattr }; Well, actually, I haven't tried it but I'm guessing that that will work. The problem is that I have other nfs directories that I don't want httpd to access, even accidentally if we ever point httpd at those directories. So... any ideas on the nfs mount with the context option? I'm running CentOS-5.1 with latest updates of everything. johnn

CentOS 5.1 on intel DQ35JO , Q35 chipsed based board
by David Hláčik 08 Dec '07

08 Dec '07

Hi, i was trying to install CentOS 5.1 on new machine based on Intel Q35 desktop board, witch 2 SATA disks (configured as RAID 1) , 8GB RAM and Intel Core2 QUADCORE. The first problem was with install - it hangs before installer startup at ACPI messages. So i installed it with ACPI=off switch. The first problem is : Dec 7 09:54:01 vmhost1 kernel: BIOS bug, no explicit IRQ entries, using default mptable. (tell your hw vendor) Dec 7 09:54:01 vmhost1 kernel: Processors: 1 Which kernel should i use? I have default installed kernel. The second problem is with LVM (probably raid on board - in bios i switched in sata mode to raid, and created in raid utility RAID1 volume from those 2 disks: /dev/sdb1 [ 101.94 MB] Found duplicate PV hpGVb3U5Q0lxFe1LN6eJpSCJSWs0xfpu: using /dev/sdb2 not /dev/sda2 /dev/sdb2 [ 297.99 GB] LVM physical volume [root@vmhost1 archive]# What does it means and how can i fix this? Thanks a lot David Hlacik

RAID-1 strategy for a CentOS/Xen server?
by Bob Tomkins 08 Dec '07

08 Dec '07

Hi, I'm planning to migrate my current server configuration: AMD Athlon/X2 FreeBSD 62-Release 2 x 250GB HW RAID1 (all partitions RAIDed, incl. swap) to a Xen/CentOS config: AMD Athlon/X2 Dom0 CentOS 51 Xen 31 Dom1/1 FreeBSD 7 Dom1/2 CentOS 51 ... To "best preserve" RAID1 mirroring protections of OS, Data, etc *AND* optimize performance, how should I setup RAID for the "new" configurations? Should DOM0 be RAIDed? Each DOM1, as well? Should I continue to use HW RAID or switch to SW? A mix? I understand I can do any/all ... choosing the "right" option is the goal, here. Advice is appreciated. Regards, Bob Tompkins

Minimal install for CentOS 5?
by Aaron Seelye 08 Dec '07

08 Dec '07

Hello, I'm new to the linux world (long time FreeBSD user), and I'm wondering if there's an easy way to install CentOS 5 without the GUI and unnecessary services? I see there's a server cd for CentOS 4, but I didnt see anything like that for CentOS 5. Am I looking in the wrong places, or is it just necessary to manually select the minimal set of packages? Thanks, Aaron Seelye
