kernel panic: Assertion failure in __journal_unfile_buffer()
by Ulrik S. Kofod 18 Feb '06

18 Feb '06

I was just extracting a 96MB tar file ( tar -xWf backup.tar ), the cpu load was 99% for a long time. I then stopped it and tried again, but this time this popped up in my ssh session: -- Message from syslogd@rock at Sat Feb 18 00:47:05 2006 ... rock kernel: Assertion failure in __journal_unfile_buffer() at fs/jbd/transaction.c:1520: "jh->b_jlist < 9" -- A kernel panic dump is displayed on the servers monitor. Here is what I can remember: Call trace: jurnal_commit_transaction+<something> [jdb] Is the panic dump stored anywhere? When I rebooted, the raid set was dirty and it was re-synced, it did not mark a drive faulty or started using a spare, the raid set still uses the same two disks and now everything seems normal, except this is the second time it does this. It is a fresh install of Cent-OS 4.2 from the DVD image and with the latest updates from yum. The server has 4 80GB software mirrored IDE disks, 2 + 2 spares, one on each channel of a HPT374 controller. I have no idea about what to look for; I have tested the disks many times with the vendor tools and no errors have been found.

OT: Local Mirror problems, wrong paths to RPMs with yum update
by James Pifer 17 Feb '06

17 Feb '06

This week I set up a local mirror for a few dists, including Centos 4.0 and 4.2, and Fedora Core 3 and 4. I'm using a script called yum-pull. For the most part I really like the script, it automates the setup of your mirrors and tries a bunch of different mirrors when it goes out to get updates, if it fails on one it tries another. It uses the usual suspects, createrepo and repoview, among others. That being said I have it all setup, but I have the following problem. For some reason the paths are not always right when you run yum update from a workstation. I'm installing a fresh copy of centos 4.2 right now so I can test the centos mirror, but I definitely have problems with my FC3 and 4 ones. One example, if I include atrpms in my repo file, it's looking for the RPMs in this directory: http://mirror.myserver.com/repomirror/fedora/linux/4/i386/atrpms/ BUT it should be looking here: http://mirror.myserver.com/repomirror/fedora/linux/4/i386/atrpms/packages/ Can anyone tell me where this is screwed up at? The directory structure looks like this: repomirror/fedora/linux/4/i386/atrpms/headers/ repomirror/fedora/linux/4/i386/atrpms/packages/ repomirror/fedora/linux/4/i386/atrpms/repodata/ repomirror/fedora/linux/4/i386/updates/headers/ repomirror/fedora/linux/4/i386/updates/packages/ repomirror/fedora/linux/4/i386/updates/repodata/ etc. I just tried my centos4.2 mirror on the new test install and it worked ok. Still, any help understanding this is appreciated. I did some googling on createrepo but have yet to find my answer. Thanks, James

Problems with IDE RAID on specific motherboard
by Benjamin Smith 17 Feb '06

17 Feb '06

About 9 months ago, I made a policy decision to adopt RAID 1 on all systems I admin. (about 20 systems, all told) It's been a long, slow process. One of the systems is being upgraded from CentOS3 to CentOS4. It's been rock-solid stable for over a year. It's a "frankenserver" with parts from all over the place, maintained over years of active service. Currently, it's got an ASRock "M810LMR" motherboard in it. http://www.ciao.co.uk/ASRock_M810LMR__5410842 When I install the O/S (I've tried CentOS 4.0 and 4.2) with IDE RAID, it bombs, takes hours just to format the drives, and won't reboot, getting stuck at "GRUB". But, when I install the SAME TWO DRIVES without RAID, (eg: some partitions on one drive, some on the other) it works perfectly. I've tried putting both drives on separate IDE cablels, using completely different drives, and trying CentOS 4.0 and 4.2. When I try to set up IDE raid while it's taking a very long time to format the drives, I see lots of errors about DMA on the alternate consoles, and there being only one drive (unable to start RAID array, only 1 drive found) even though the installer and disk druid have no problem reporting both drives. It comes down to something like "/dev/mdN delayed until /dev/mdX is synchronized because they share physical resources"... I'm stumped, and falling back to non-RAID because this system is needed in production. And, I'm not new to using software RAID, I've been using it for years without issue. Any idea what's going on? -- "The best way to predict the future is to invent it." - XEROX PARC slogan, circa 1978

Postgresql 8.1.x on CentOS 3.6
by Matt Arnilo S. Baluyos (Mailing Lists) 17 Feb '06

17 Feb '06

Hello everyone, Does anyone know if there are any Postgresql 8.1.3 RPMs for CentOS 3.6? I've looked at the Postgresql website but I couldn't find anything under RHEL3/CentOS3. I've tried installing the RHEL4 RPMs which seem to work. Unfortunately, I'm getting errors whenever I try to compile PHP5 from source. Thanks and Best Regards, Matt -- Stand before it and there is no beginning. Follow it and there is no end. Stay with the ancient Tao, Move with the present.

clock, centos 4 and dual core?
by Ugo Bellavance 17 Feb '06

17 Feb '06

Hi, I have a dual core athlon server and it is gaining 1 day every 2 days w/o time sync. Even with ntpd running, the time is not under control. I must put a very frequent cronjob of 'ntpdate' to keep the time under control. This creates big problems since winbind eventually stops working so my users can't access their data. Any ideas? -- Ugo -> Please don't send a copy of your reply by e-mail. I read the list. -> Please avoid top-posting, long signatures and HTML, and cut the irrelevant parts in your replies.

Re: [CentOS] After install centos does not find hardrives (SATA)

actually its dosnt even make it to Grub, its the EMI menu on Intel servers... so I guess it cannot even find a proper boot device.. ill have to do more research on the issue. if you have any ideas why that would also be great help. thanks alot, Quoting Aleksandar Milivojevic <alex(a)milivojevic.org>: > Quoting Nathan <lists(a)netdigix.com>: > > > no its the prompt centos goes to when it cannot find anything to boot to. > > So it's the grub prompt most likely.

I suggested it, and not just for common SSH on CentOS questions but for anything that's, well, frequently asked on the list and at least vaguely CentOS related. Would a WiKi (I'd vote MediaWiki but only because I already know the markup and have a bunch of stuff I could drop in :)) similar to the MailScanner one be a good idea? Will.
