SYNOPSIS¶

--commandprofile String --config String -d|--debug --driverloaded y|n -f|--file String --force -h|--help -l|--list --lockopt String --longhelp -M|--metadatatype lvm2 --nolocking --profile String -q|--quiet -t|--test -v|--verbose --version -y|--yes

DESCRIPTION¶

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¶

vgcfgrestore VG

Restore VG metadata from specified file.

vgcfgrestore -f|--file String VG

List all VG metadata backups.

vgcfgrestore -l|--list VG

List one VG metadata backup file.

vgcfgrestore -l|--list -f|--file String

Common options for command:

Common options for lvm:

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 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.

--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.

--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¶

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.)
