RECOVERY

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