Saw this covered slightly back in May
(
https://fedorahosted.org/pipermail/cobbler/2010-May/005623.html), but
haven't seen any resolution in any place that I've looked.
What is happening is that if we attempt to koan --replace-self a Centos
5.5 system ( on physical hardware, not a xen or kvm instance), it hangs
during reformatting of the drives. The drives are single SSDs, and are
not exposed as a RAID disk or anything else.
From my kickstart I do have the following that should be relevant:
# Partition clearing information
clearpart --all --initlabel
# Clear the Master Boot Record
zerombr
#autopart this
autopart
NOTE: these 3 lines aren't all next to each other like this, but are in
their relevant sections of the kickstart
The first time this is run on a brand new system, the following
formatting happens:
....
13:34:25 INFO : formatting swap as swap
13:34:25 INFO : formatting / as ext3
13:34:25 INFO : Format command: ['/usr/sbin/mke2fs',
'/dev/VolGroup00/LogVol00', '-i', '4096', '-j']
13:34:58 INFO : formatting /boot as ext3
13:34:58 INFO : Format command: ['/usr/sbin/mke2fs', '/tmp/sda1',
'-i', '4096', '-j']
13:34:58 DEBUG : starting mpaths
...
it then continues on and all is well.
if we go to koan --replace-self this host. With no changes to the
kickstart at all. We see the following:
....
00:12:52 DEBUG : DiskSet.skippedDisks: []
00:12:52 DEBUG : done starting mpaths. Drivelist: ['sda']
00:12:52 DEBUG : adding drive sda to disk list
00:12:53 INFO : formatting swap as swap
00:12:53 INFO : formatting / as ext3
00:12:53 INFO : Format command: ['/usr/sbin/mke2fs',
'/dev/VolGroup00/LogVol00', '-i', '4096', '-j']
Then it hangs. Watching the screen during this time produces random
text that looks Greek. The whole system hangs and ctrl-alt-del doesn't
work, it requires a power reset.
We just started moving onto Centos 5.5, so I'm more willing to put my
money into anaconda changes, or something else hit by anaconda than I am
cobbler, but I figured it was worth while to ask here. Anyone else seen
anything like this?
Thanks,
