[linux-lvm] After power outtage my vg is gone

[Klaus Pedersen]

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
