how to debug random server reboots
by Rudi Ahlers 03 Jun '09

03 Jun '09

Hi all, One of our CentOS 5.3 randomly reboots, at different times of the day, and I can't see why it's doing it. I have looked through the logs, but don't see any thing in there that shows me why it has rebooted. How can I debug this? Here's a snipped from the log, around the time of the reboot: Jun 2 14:59:59 usaxen02 kernel: EXT3-fs: mounted filesystem with ordered data mode. Jun 2 15:00:06 usaxen02 kernel: kjournald starting.

Re: [CentOS] Random server reboot after update to CentOS 5.3

Sometimes it will go for days without rebooting then today it has rebooted 6 times at random times. I have modified grub.conf to go back to 2.6.18-92.1.22.el5xen on my dom0 and my only domU so we will see what happens (or hopefully doesn't happen) the next few days. I have a 3.0 P4 CPU with HT that does not support 64-bit so it's running an i686 kernel. It does have a Broadcom NIC like an earlier post was suspicious of: 02:08.0 Ethernet controller: Intel Corporation 82562EZ 10/100 Ethernet Controller (rev 02) 02:09.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5703X Gigabit Ethernet (rev 02) I have upgraded about 8 other servers with no random reboot problems but they are all running on a newer processors with a 64-bit kernel. -- Dave Jones

Removing old kernels
by Frank M. Ramaekers 03 Jun '09

03 Jun '09

I have the following kernels on my /boot: 2.6.18-128.1.6 2.6.18-92.1.18 2.6.18-92.1.22 I'm low on /boot space and need to remove the oldest version. It appears that I cannot use yum to remove since all of the versions are the same (only the release is different). I believe that I can use rpm to remove the old version, but I also need to remove them from the grub.conf. Any other considerations and/or methods? Frank M.

This is what we all *believe* we know (e.g. "5"-current is now "5.3"+updates). However, TUV seems to have had a different opinion st some point in the past, or at least this is what Johnny understood. Read carefully this: http://bugs.centos.org/view.php?id=2481 Excerpts: ============================== we are trying something new to correspond to an upcoming 5.y.z release scheme from upstream. in the scheme, there will be a 5.1.z and 5.2.z tree ... those trees will be available for an extended period of time (5.1 and 5.2 ... each with different updates). ============================== we are not exactly sure how or even when upstream will do this z tree thing ============================== we do not have any intention of doing 5.1.1 or 5.1.2, just 5.1 ... and maintaining it while it is maintained upstream. ============================== Also, we do not plan to - as Johnny has already pointed out - do any 5.1.1 or 5.1.2 or 5.1.3 releases, since again that would be counter productive and leave users with a false sense of security thinking they have the latest patch levels for each machine - when they might not. ============================== So there *should* have existed: * 5.1-only updates issued post-5.2; * 5.1-only and 5.2-only updates issued post-5.3; etc. AFAIK, this never happened. Is the 5.x.z tree concept dead-before-birth?! Thanks, R-C __________________________________________________________________ Looking for the perfect gift?

As per the upstream vendors errata support policy, updates for CentOS-2 ended on May 31, 2009. It is recommended that any system still running CentOS 2 should be upgraded to a more recent version of CentOS to ensure continued security and bug fix support. Upgrade information can be found here http://wiki.centos.org/MigratingTwoToFive More details are available from the RedHat web site at https://rhn.redhat.com/errata/rh21as-errata.html Thank you to everyone who helped make this project possible. The CAOS and CentOS projects, the unnamed upstream vendor and of course, the users who gave it a reason to exist. After 5 years at the helm of CentOS-2, I look forward to working on some new projects both CentOS and elsewhere.

Harware vs Kernel RAID (was Re: External SATA enclosures: SiI3124 and CentOS 5?)

I've read a lot of different reports that suggest at this point in time, kernel software raid is in most cases better than controller raid. The basic argument seems to be that CPU's are fast enough now that the limitation on throughput is the drive itself, and that SATA resolved the bottleneck that PATA caused with kernel raid. The arguments then go on to give numerous examples where a failing hardware raid controller CAUSED data loss, where a raid card died and an identical raid card had to be scrounged from eBay to even read the data on the drives, etc. - problems that apparently don't happen with kernel software raid. The main exception I've seen to using software raid are high availability setups where a separate external unit ($$$) provides the same hard disk to multiple servers. Then the raid can't really be in the kernel but has to be in the hardware. I'd be very interested in hearing opinions on this subject.
