DESCRIPTION         top

       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         top

       Restore VG metadata from last backup.

           [    --version ]

OPTIONS         top

       --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.

       --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
              historical 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
              --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         top

       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 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         top

       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         top

       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.
