     DESCRIPTION
          vgcfgrestore restores the metadata of a VG from a text  back
          up  file  produced  by  vgcfgbackup. This writes VG metadata
          onto the devices specifed in back up file.

          A back up file can be specified with --file.  If  no  backup
          file  is  specified, the most recent one is used. Use --list
          for a list of the available back up and archive files  of  a
          VG.

          WARNING: When a VG contains  thin  pools,  changes  to  thin
          metadata cannot be reverted, and data loss may occur if thin
          metadata has  changed.  The  force  option  is  required  to
          restore in this case.

     USAGE
          Restore VG metadata from last backup.

          vgcfgrestore VG
              [ COMMON_OPTIONS ]
          -

          Restore VG metadata from specified file.

     OPTIONS
          --commandprofile String
               The command profile to use for command configuration.
               See lvm.conf(5) for more information about profiles.

          --config String
               Config settings for the command. These override
               lvm.conf settings.  The String arg uses the same format
               as lvm.conf, or may use section/field syntax.  See
               lvm.conf(5) for more information about config.

          -d|--debug ...
               Set debug level. Repeat from 1 to 6 times to increase
               the detail of messages sent to the log file and/or
               syslog (if configured).

          --driverloaded y|n
               If set to no, the command will not attempt to use
               device-mapper.  For testing and debugging.

          -f|--file String
               Read metadata backup from the named file.  Usually this
               file was created by vgcfgbackup.

          --force ...
               Force metadata restore even with thin pool LVs.  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.

          -h|--help
               Display help text.

          -l|--list
               List metadata backup and archive files pertaining to
               the VG.  May be used with --file. Does not restore the
               VG.

          --lockopt String
               Used to pass options for special cases to lvmlockd.
               See lvmlockd(8) for more information.

          --longhelp
               Display long help text.

          -M|--metadatatype lvm2
               Specifies the type of on-disk metadata to use.  lvm2
               (or just 2) is the current, standard format.  lvm1 (or
               just 1) is no longer used.

          --nolocking
               Disable locking.

          --profile String
               An alias for --commandprofile or --metadataprofile,
               depending on the command.

          -q|--quiet ...
               Suppress output and log messages. Overrides --debug and
               --verbose.  Repeat once to also suppress any prompts
               with answer 'no'.

          -t|--test
               Run in test mode. Commands will not update metadata.
               This is implemented by disabling all metadata writing
               but nevertheless returning success to the calling
               function. This may lead to unusual error messages in

               multi-stage operations if a tool relies on reading back
               metadata it believes has changed but hasn't.

          -v|--verbose ...
               Set verbose level. Repeat from 1 to 4 times to increase
               the detail of messages sent to stdout and stderr.

          --version
               Display version information.

          -y|--yes
               Do not prompt for confirmation interactively but always
               assume the answer yes. Use with extreme caution.  (For
               automatic no, see -qq.)

     VARIABLES
          VG
               Volume Group name.  See lvm(8) for valid names.

          String
               See the option description for  information  about  the
               string content.

          Size[UNIT]
               Size is an input number that accepts an optional  unit.
               Input  units  are  always  treated  as base two values,
               regardless of capitalization, e.g.  'k'  and  'K'  both
               refer  to 1024.  The default input unit is specified by
               letter,  followed  by  |UNIT.   UNIT  represents  other
               possible  input units: bBsSkKmMgGtTpPeE.  b|B is bytes,
               s|S is sectors of 512 bytes, k|K is KiB,  m|M  is  MiB,
               g|G  is GiB, t|T is TiB, p|P is PiB, e|E is EiB.  (This
               should not be confused with the output control --units,
               where capital letters mean multiple of 1000.)

     ENVIRONMENT VARIABLES
          See lvm(8) for information about environment variables  used
          by   lvm.    For   example,  LVM_VG_NAME  can  generally  be
          substituted for a required VG parameter.

     NOTES
          To replace PVs, vgdisplay --partial --verbose will show  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 VG's metadata.
