DESCRIPTION
vgcfgrestore restores the metadata of a VG from a text back up file produced by vgcfg-
backup. 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 re-
cent 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.

OPTIONS
--commandprofile String
The command profile to use for command configuration. See lvm.conf(5) for more in-
formation 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 vgcfg-
backup.
--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 in-
formation.
--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 dis-
abling all metadata writing but nevertheless returning success to the calling func-
tion. 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 re-
fer 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 argu-
ments 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.
