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.
