RECOVERY

28       Use pvscan(8) to see which PVs lost their  metadata.   Run  pvcreate(8)
29       with  the  --uuid and --restorefile options on each such PV to reformat
30       it as it was, using the archive file that vgconvert(8) created  at  the
31       start  of the procedure.  Finally run vgcfgrestore(8) with that archive
32       file to restore the original metadata.
