DESCRIPTION

       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.

OPTIONS

       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.

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

REPLACING PHYSICAL VOLUMES

       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 initialise 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.
