[SOLVED] Update to Centos 6.4 results in no initramfs file

[mphelpsmd]

I updated my system from Centos 6.3 to 6.4 using the command:

yum update


That resulted in a kernel panic similar to one that has been described here before:

md: Waiting for all devices to be available before autodetect
md: If you don't use raid, use raid=noautodetect
md: Autodetecting RAID arrays.
md: Scanned 0 and added 0 devices.
md: Autorun ...
md: ... autorun DONE.
VFS: Cannot open root device "UUID=XXX" or unknown-block(0,0)
Please append a correct "root=" boot option; here are the available partitions:
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
Pid: 1, comm: swapper Not tainted 2.6.32-358.6.2.el6.x86_64 #1
Call Trace:

[] ? child_rip+0xa/0x20
[] ? kernel_init+0x0/0x2fe
[] ? child_rip+0x0/0x20

I was able to boot into an older version of the kernel (2.6.2-220.23.1.el6.x86_64), though.

I attempted:
yum reinstall kernel-2.6.2-358.6.2.el6.x86_64

This command completed, but with a warning:
Non-fatal POSTTRANS scriptlet failure in rpm package kernel-2.6.32-358.6.2.el6.x86_64

Curiously, there is no initramfs-2.6.32-358.6.2.el6.x86_64 to go with the vmlinuz-2.6.32-358.6.2.el6.x86_64 file.

So I attempted to make one:
dracut --mdadmconf --verbose initramfs-2.6.32-358.6.2.el6.x86_64 2.6.32-358.6.2.el6.x86_64

This results in:
...
I: Installing /sbin/blockdev
I: Installing /usr/share/dracut/modules.d/90dmsquash-live/parse-dmsquash-live.sh
I: Installing /usr/share/dracut/modules.d/90dmsquash-live/dmsquash-liveiso-genrules.sh

I: Installing /etc/modprobe.d/dist.conf
I: Installing /etc/modprobe.d/anaconda.conf
I: Installing /etc/modprobe.d/dist-oss.conf
Segmentation fault (core dumped)


So I can't seem to make the initramfs for this kernel.

Any suggestions?

# It is esp. important, to have correct metadata, for distributions like

You have several repositories installed, and you're not using Priorities. That's not good. :-(

I wasn't aware of repository priorities. I will have to Google this and learn more about it. Most of the repositories are disabled. (I added the MondoLinux ones when I needed to make an emergency boot disk until I figured out that I could just get by with the older kernels. I have since disabled the Mondo repos.)

I went back and enabled only the major repositories, then did a yum remove (failed kernel versions here), yum clean all, and yum update again.

Still same problem: The later kernels produce a kernel panic on booting up, and I still can't create their initramfs files because dracut still crashes with a segmentation violation.

Is it possible that I have some of the support utilities that got out of sync with the kernels? I updated from 6.2 to 6.3, then 6.4. I have to use the kernel from 6.2 now in order for the system to boot up.

Thanks,

Mike

This is a strange issue. What is the latest kernel that works? The ones from CentOS 6.2? Is everything else up-to-date?

[toracat]

Perhaps, try adding the -H flag (host only) to the dracut command ?

[mphelpsmd]

Gotta love strange issues. The kernel panic I get is similar to one that has been discussed before (see http://bugs.centos.org/view.php?id=6327), although mine is not resolved with a yum reinstall kernel... command.

Only the kernel 2.6.32-220 series work for me now. The 2.6.32-358 and I believe 2.6.32-279 (or something similar to that, I no longer have it on my system) crash with a kernel panic on boot.

The -H flag on dracut has no effect; there is still a crash with a Segmentation fault.

I'm not sure if this information helps, but when I'm using dracut with the --verbose option, the core dump always occurs after the same message:

I: Installing /etc/modprobe.d/dist-oss.conf

The contents of that file are as follows:

[root@ares boot]# cat /etc/modprobe.d/dist-oss.conf
# OSS Sound Support
# This has been disabled in F11 onwards because it can interfere with the
# PulseAudio sound service (a legacy OSS application can prevent PulseAudio
# applications from playing sound by preventing PulseAudio from (re-)opening
# the sound device). To re-enable support, uncomment the following line:
#
# install snd-pcm /sbin/modprobe --ignore-install snd-pcm && /sbin/modprobe snd-pcm-oss && /sbin/modprobe snd-seq-device && /sbin/modprobe snd-seq-oss


As you can see, everything is commented out.

Needless to say, these kernel panics with updating the system has shaken my faith a little in yum and enterprise-grade software.

Would there be an advantage to, say, downgrading to 6.3 or something to ensure all the pieces are in sync? I've spent about a year custom configuring this machine, so I'm obviously not too excited to do a fresh reinstall.

I'm using a basic SuperMicro server. The only mildly odd things I'm doing are software RAID 1 and link aggregation with two of the ethernet ports.

Thanks,

Mike

I tried rerunning your dracut command here to see what came after the file you mention in case it wasn't that one but the one that came next that was causing the crash. Unfortunately it lists my files in a different order to yours so I don't think we can guess from that. But can you look at the files listed in /etc/modprobe.d and see if there are any that it didn't process yet? Maybe the problem lies in one of the ones it didn't list? My dis-oss.conf file looks identical to yours.

[TrevorH]

Can you install, if it isn't already, strace and run dracut using that. I'd omit the verbose bit on this invocation as strace will just have more work to do tracing the debugging messages. Use something like

[code]
# strace -f -o /tmp/dracut-strace.txt dracut --mdadmconf initramfs-2.6.32-358.6.2.el6.x86_64 2.6.32-358.6.2.el6.x86_64
[/code]

Once it crashes, look at the output file in /tmp and go backwards from the end until you find the segfault and then look at what it was doing immediately prior to that. If you need help interpreting the strace then use pastebin.centos.org and send, say, the last 2 or 300 lines of the file there and paste the link here.

[mphelpsmd]

OK, I'll try this shortly.

In the meantime, I looked at the /etc/modprobe.d directory. The only thing unusual I found was that I have a bonding.conf file that looks like this:


[root@ares modprobe.d]# cat bonding.conf
#!/etc/modprobe.d/bonding.conf

alias bond0 bonding



When I Google'd how to do link aggregation, this was one of the steps that came up as part of the process. (The link aggregation works, by the way.) I'm wondering if this is what's giving dracut a fit. Perhaps if I try commenting out the active line in this configuration, then run yum update kernel again, maybe that would work?

I'll try, and if that doesn't work I'll play with the strace. Either way, I feel that this is a bug in dracut. It shouldn't segfault.
