[linux-lvm] Lost all logical volumes in two volume groups?

["Jimisola Laursen" <public@jimisola.com>]

Hi!

After a failed Mandriva upgrade I can no longer use my two LVM (vg01 and vg02).
When the upgrade failed I unplugged my disks after two-three boots where 
ReiserFS found errors until I had reinstalled my system (with OpenSuse).

I just plugged in my disks again and the LVM partitions are recognized, but 
there are no LVs!
Is there anyway for me to fix this?

I have an old copy of /etc/lvm with archive and backup directories including 
vg01_00000.vg and vg01_00001.vg.
No .vg files for vg02 though, but that VG is less important than the vg01 one.

VG system: current OpenSuse system
VG vg01: shows no LV (have .vg files)
VG vg02: shows no LV (have no .vg files)

All partitions are ReiserFS.

Regards,
Jimisola
