NAME

   vgcfgrestore --- restore volume group descriptor area

SYNOPSIS

   vgcfgrestore  [--commandprofile  ProfileName]  [-d|--debug]  [-f|--file
   <filename>]  [--force]  [-l[l]|--list]  [-h|--help]  [-M|--metadatatype
   1|2] [-t|--test] [-v|--verbose] VolumeGroupName

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.
