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.
Restore VG metadata from last backup.

[ --version ]
--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.)
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.)
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.
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.
