Also, just an FYI in case anyone else runs across this thread... to get
my filesystem back (pvscan didn't detect the LVM at all):
# pvcreate --uuid 3HpAVg-fRz0-HWXp-EFxK-khVO-IvN6-J4a6w1 /dev/sdb
(Found the old UUID by examining the /etc/lvm/backup directory)
# vgcfgrestore FTP1
# vgchange -ay FTP1
# fsck.ext3 /dev/FTP1/LogVol00
# mount -a
Back in action!
