After power outtage my vg is gone

I'm using Debian Linux on 2.4.6 (and whatever version of LVM that comes with it).
After accidentaly pushing the power switch on my Linux server and starting it up again, I have problems mounting my vg again.

This is what happens :

Vault:/home/ultra# mount /glftpd/site
mount: /dev/site_vg/lvol1 is not a valid block device
Vault:/home/ultra# vgscan
vgscan -- reading all physical volumes (this may take a while...)
vgscan -- found inactive volume group "site_vg"
vgscan -- ERROR "vg_read_with_pv_and_lv(): allocated LE of LV" can't get
data of volume group "site_vg" from physical volume(s)
vgscan -- ERROR "vg_read_with_pv_and_lv(): allocated LE of LV" creating
"/etc/lvmtab" and "/etc/lvmtab.d"

Vault:/home/ultra#

I read through the archive of the list because I am absolutely sure I am not the first who had this problem. I read some stuff about using the uuid_fixer tool, bit as far as I was able to read, the problem that fixes only shows up after extending the VG (Which I did a week or so, ago), and only for kernels up to 2.4.5.
Is this true ?

Vault:~/uuid_fixer# ./uuid_fixer /dev/hda8 /dev/hdb1

UUIDs discovered:
W9tkR7eq026WBMCBrUCdebI32vRyFuLn
u5vBzCHwu5mjAt5yN0lS4Ecrto1jI9NZ

I tried running it anyway, and after that I ran vgscan - and the same problems showed up.

What do I do to recoved my data ?

Any help is greatly appreciated

Klaus,

you probably need to update to LVM 1.0.1 rc4 to address this then (You can get the LVM code from CVS at www.sistina.com).

I am not sure if you need to update the kernel part of LVM in Debian though.

Just compile the library and tools as described in LVMs INSTALL file and try. If that finds your VG (which I hope ;-) and you still see other problems, please either get the recent Alan Cox kernel (which is up to date IRT LVM) *or* patch Linus kernel following the instructions in LVMs INSTALL and PATCHES/README files.
