I found this which looks as though it may help. I'll let you know:
It didn't but it did contain a link to <http://www.tldp.org/HOWTO/LVM-HOWTO/index.html>, which contains <http://www.tldp.org/HOWTO/LVM-HOWTO/recovermetadata.html> and that gave me enough of a hint to be able to fix the problem. It needed a sequence of three commands: # pvcreate --uuid "Fb8U24-BKDl-IOkW-sKxT-VhcW-n274-HnOj40" --restorefile /etc/lvm/backup/backup /dev/sdb # vgcfgrestore --file /etc/lvm/backup/backup backup # vgchange -ay backup 'backup' is the name of my missing volume group. It also happens to be the name of a directory that LVM uses. /dev/sdb is the device that is the missing physical volume, which contains the entire volume group. The uuid to use was found in /etc/lvm/backup/backup. I've just fscked one of the filesystems so I'm pretty convinced it's now working again but I'll fsck them all to be sure. I'm also pretty convinced that the problem did arise by grub overwriting the LVM metadata.
