[linux-lvm] lvm 1.0.3 kernel panic



Hi experts,

I added a new hard disk to my system and created it entirely as a new logical volume. Mounting unmounting everything worked until reboot. It stops now with kerel panic and lines like:

(null) -- ERROR 2 writing volume group backup file /etc/lvmtab.d/vg01.tmp
      vg_cfgbackup.c [line271]

vgscan -- ERROR: unable to do a backup of volume group vg01
vgscan -- ERROR: lvm_tab_vg_remove(): unlink" removing volume group "vg01" from "/etc/lvmtab"


...

Activating volume groups
   vgchange - no volume groups found

I understand the kernel panic if lvm is unable to find the volume group vg01 because that's my root system. But I don't get the first error.
I rebooted with my Redhat Installation disk: linux rescue
and can activate the volume group by hand and mount the file systems. So it looks to me everything is consistent in the filesystem.


So since I am pretty new to lvm, which output do you additional need to help me?

Thanks in advance,
Stephanus
