Yes, I was referring to LVM2. LVM1 doesn't have the --removemissing flag
to vgreduce.

By default LVM1 should make a backup of the volume group metadata before
the vgextend command adds a new PV- it's worth checking /etc/lvmconf to
see if you can restore the old metadata.

Use vgcfgrestore -f <file> -n <vgname> -ll to see the physical & logical
volumes in the backups and restore from the last good one (only the
metadata is restored - data in the LVs remains unchanged).

See the man page for vgcfgbackup/vgcfgrestore for more details.

Regards,

Bryn.
