Well, it's not quite that simple - if something scribbles over your LVM metadata (i've never seen this happen where it wasn't user error), you need to do quite a bit more work to get things back so you can activate your LVs so you can fsck your ext3 partition. It usually involves at least running a vgcfgrestore against the backup file in /etc/lvm/backup. So yes, it can be more complicated if the lvm metadata gets broken - but this is similar to what happens if the partition table gets busted on a normal disk. -- AJ Lewis Voice: 612-638-0500 Red Hat Inc.
