[linux-lvm] LVM metadata recovery

[Alex Matviychuk]

Hello,

I've been searching the net and this mailing list for quite some time 
for a way to recover metadata without having access to any backups. I 
completely screwed up and forgot to backup or export my lvm settings 
when I reinstalled my operating system. Now I can see my volume group, 
but when I try to activate it I get:

  Volume group vg00 metadata is inconsistent
  Volume group for uuid not found: 
fhRVK5ZTwTOdTQpgF8oyAESEj8LYNRJy1P1jjdkNCV1WhYwfv9rxpnExXvNu13T6
  0 logical volume(s) in volume group "vg00" now active

If I run pvscan I get:
  PV /dev/hda3   VG vg00   lvm2 [128.54 GB / 0    free]
  PV /dev/hdd1   VG vg00   lvm2 [74.52 GB / 0    free]
  PV /dev/hdb1   VG vg00   lvm2 [186.30 GB / 29.36 GB free]
  Total: 3 [389.36 GB] / in use: 3 [389.36 GB] / in no VG: 0 [0   ]

and vgscan returns:
  Reading all physical volumes.  This may take a while...
  Found volume group "vg00" using metadata type lvm2

What are my options if any?

Thanks for your time,
Alex Matviychuk

p.s. Here is some more debug output:
