I gave it a try and that did not fix it.

vgcfgrestore lnxvg
  Incorrect metadata area header checksum
  Restored volume group lnxvg


and I tried:

vgcfgrestore -l lnxvg
  No archives found in /etc/lvm/archive.

  File:         /etc/lvm/backup/lnxvg
  Incorrect metadata area header checksum
  VG name:      lnxvg
  Description:  Created *after* executing '/sbin/vgcfgbackup'
  Backup Time:  Sat Feb 25 21:02:37 2006


I think it does not sound too good.  :(

Something else we could try.

TIA,
