I'm trying to get kdump working on our RHEL5 servers,

it starts booting the kdump environment, but quickly
fails with messages about (from memory):
Imported volume group "rootvg" OK.
Failed to find logical volume /dev/mapper/-swaplv
Failed to find logical volume /dev/mapper/-rootlv
Failed to find logical volume /dev/mapper/-varlv
Failed to find logical volume /dev/mapper/-locallv
and dumps me into the shell. I checked the /dev/mapper
directory, and found the expected /dev/mapper/rootvg-swaplv,
/dev/mapper/rootvg-rootlv, etc.. So the problem seems to be
that kdump is eating up the "rootvg"-part of the device name.
Is this a known problem? Any ideas for how to fix it ?
Another thing.. anybody know if it's possible the redirect
the kdump output to netconsole ? That would be very nice
for capturing the reason when it fails..

You can expect to get better kexec/kdump-specific help on
either of these two lists:
http://lists.infradead.org/mailman/listinfo/kexec
http://post-office.corp.redhat.com/mailman/listinfo/kexec-kdump-list
Although there's a huge member cross-over between this list
and the two above, the primary purpose of this list is the
crash utility itself.
