Red Hat Bugzilla – Bug 99356
Raid kernel modules missing in NFS install
Last modified: 2007-04-18 12:55:44 EDT
Description of problem:
The raid1 module is not loaded when doing a NFS (and possibly other type)
install with RAID-1 partitions. This causes the installer to exit with a fatal
error, due to mke2fs failing, which in turn is due to mkraid failing. mkraid
puts the message "Personality 3 not loaded" in the syslog, which indicates that
the raid1 module isn't loaded. I belive this is also a problem with raid0, raid5.
This problem doesn't occur when doing a CD install.
mkraid also doesn't work when doing a NFS rescue either.
Steps to Reproduce:
1. Perform a Redhat 9 NFS installation createing a RAID-1 partition
Actual Results: Installer fails with fatal error ("Personality 3 not loaded" in
Expected Results: Everything should work :)
We always attempt to load all of the RAID modules. Does your boot disk use a
different kernel version than the modules on the second stage?
Could you attach both /tmp/anaconda.log and /tmp/syslog?
One blaring omission I forgot to mention, was that I was using the Dell RH9
Install CD, which I think uses an updated kernel to fix some USB bug. I'll have
another go tomorrow with the normal redhat boot disks and see how I go. I'll
keep you posted.
I do remember I encountered same problem when sitting my RHCE exam, which caused
me great greif, but that was with Redhat 8.
I don't have any machines that I'm able to nuke anymore, so I'm unable to verify
that the dell cd's updated kernel was the problem, but I'm guessing it probably
was, otherwise I'm sure someone else would have reported the bug by now.
If there's an updated kernel, there must be a complete updated installer tree to
go with it, otherwise, you will not have matching modules in stage2. If Dell is
providing things where this isn't the case, you will have to go to them for
support of it -- we can only support what we've shipped.
