[linux-lvm] Corrupted LVM, need help

[Greg Freemyer]

All,

I have a LVM based data disk with 3 LVs.  My OS disks are _not_ LVM based.

We had a lightning storm over the weekend, and an old kernel (2.4.18) got 
booted when the machine was powered back on.  I have 2.4.19 running again now.

Now I get the following:

SuSEbox:~ # pvscan
pvscan -- reading all physical volumes (this may take a while...)
pvscan -- inactive PV "/dev/sda1"  is associated to unknown VG "TruStore-Data" 
(run vgscan)
pvscan -- total: 1 [55.91 GB] / in use: 1 [55.91 GB] / in no VG: 0 [0]

SuSEbox:~ # vgscan
vgscan -- reading all physical volumes (this may take a while...)
vgscan -- ERROR "lv_read_all_lv(): number of LV" can't get data of volume group 
"TruStore-Data" from physical volume(s)
vgscan -- "/etc/lvmtab" and "/etc/lvmtab.d" successfully created
vgscan -- WARNING: This program does not do a VGDA backup of your volume group

SuSEbox:~ # 

Any ideas on how to restore my LVM config tables (VGDAs ??).  I think LVM keeps 
backups somewhere.
