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 specified 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

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(5)
              settings.    The   String  arg  uses  the  same  format  as
              lvm.conf(5),  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).

       --devices PV
              Devices  that  the  command  can  use.  This  option can be
              repeated or accepts a comma separated list of devices. This
              overrides the devices file.

       --devicesfile String
              A file listing devices that LVM should use.  The file  must
              exist   in   /etc/lvm/devices/  and  is  managed  with  the
              lvmdevices(8)  command.   This  overrides  the  lvm.conf(5)
              devices/devicesfile and devices/use_devicesfile settings.

       --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.

       --journal String
              Record  information   in   the   systemd   journal.    This
              information  is  in  addition to information enabled by the
              lvm.conf log/journal setting.  command: record  information
              about  the  command.   output:  record  the default command
              output.  debug: record full command debugging.

       -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.

       --nohints
              Do not use the hints file to  locate  devices  for  PVs.  A
              command  may  read  more devices to find PVs when hints are
              not used. The command will still perform standard hint file
              invalidation where appropriate.

       --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         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: 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         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.
