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.

           [    --longhelp ]
           [    --profile String ]
           [    --version ]
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 set-
              tings.  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 lvm-
              lockd(8) for more information.
       --longhelp
              Display long help text.
       -M|--metadatatype lvm2|lvm1
              Specifies the type of on-disk metadata to use.  lvm2 (or just 2)
              is the current, standard format.  lvm1 (or just 1) is a histori-
              cal format that can be used for accessing old data.
       --profile String
              An alias for --commandprofile or --metadataprofile, depending on
              the command.
       -q|--quiet ...
              Suppress output and log messages. Overrides --debug and --ver-
              bose.  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 con-
              tent.
       Size[UNIT]
              Size  is  an  input number that accepts an optional unit.  Input
              units are always treated as base two values, regardless of capi-
              talization,  e.g.  'k'  and 'K' both refer to 1024.  The default
              input unit is specified by letter, followed by |UNIT.  UNIT rep-
              resents  other  possible  input units: bBsSkKmMgGtTpPeE.  b|B is
              bytes, s|S is sectors of 512 bytes, k|K  is  kilobytes,  m|M  is
              megabytes, g|G is gigabytes, t|T is terabytes, p|P is petabytes,
              e|E is exabytes.  (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 appro-
       priate)  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.
