I'm trying to get kdump working on our RHEL5 servers,
but am failing to get any dumps. After I trigger a crash,
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..
