Common causes:
  Mixed-up partitioning (e.g. device is partitioned yet the PV was 
installed on the whole disk; fix - remove unused partition table)
  pvcreate was run against devices inside the PV
    fix: run pvcreate again with -u to put the uuids back on all the
         devices, followed by vgcfgrestore (once per VG) to put 
         the metadata back from current backup
