       vgcfgrestore allows you to restore the metadata of VolumeGroupName from
       a text backup file produced by vgcfgbackup.  You can specify  a	backup
       file  with --file.  If no backup file is specified, the most recent one
       is used.	 Use --list for a list of the  available  backup  and  archive
       files of VolumeGroupName.

       See lvm(8) for common options.

       -l, --list
	      List  files  pertaining  to VolumeGroupName List metadata backup
	      and archive files pertaining to VolumeGroupName.	 May  be  used
	      with the -f option.  Does not restore VolumeGroupName.

       -f, --file filename
	      Name  of LVM metadata backup file Specifies a metadata backup or
	      archive file to be used for  restoring  VolumeGroupName.	 Often
	      this file has been created with vgcfgbackup.

	      Necessary to restore metadata with thin pool volumes.
	      WARNING:	Use  with extreme caution.  Most changes to thin meta‐
	      data cannot be reverted.	You may lose data if you restore meta‐
	      data  that  does	not  match  the thin pool kernel metadata pre‐

       vgdisplay --partial --verbose will show you the UUIDs and sizes of  any
       PVs that are no longer present.	If a PV in the VG is lost and you wish
       to substitute another of the  same  size,  use  pvcreate	 --restorefile
       filename --uuid uuid (plus additional arguments as appropriate) to ini‐
       tialise it with the same UUID as the missing PV.	 Repeat for all	 other
       missing	PVs  in	 the  VG.   Then  use  vgcfgrestore --file filename to
       restore the volume group's metadata.
