VGRENAME(8) System Manager's Manual VGRENAME(8)
NAME
vgrename - Rename a volume group
SYNOPSIS
vgrename position_args
[ option_args ]
DESCRIPTION
vgrename renames a VG.
All VGs visible to a system need to have different names, otherwise
many LVM commands will refuse to run or give warning messages. VGs with
the same name can occur when disks are moved between machines, or fil-
ters are changed. If a newly connected disk has a VG with the same name
as the VG containing the root filesystem, the machine may not boot cor-
rectly. When two VGs have the same name, the VG UUID can be used in
place of the source VG name.
USAGE
Rename a VG.
vgrename VG VG_new
[ COMMON_OPTIONS ]
Rename a VG by specifying the VG UUID.
vgrename String VG_new
[ COMMON_OPTIONS ]
Common options for command:
[ -A|--autobackup y|n ]
[ -f|--force ]
[ --reportformat basic|json ]
Common options for lvm:
[ -d|--debug ]
[ -h|--help ]
[ -q|--quiet ]
[ -t|--test ]
[ -v|--verbose ]
[ -y|--yes ]
[ --commandprofile String ]
[ --config String ]
[ --driverloaded y|n ]
[ --lockopt String ]
[ --longhelp ]
[ --nolocking ]
[ --profile String ]
[ --version ]
OPTIONS
-A|--autobackup y|n
Specifies if metadata should be backed up automatically after a
change. Enabling this is strongly advised! See vgcfgbackup(8)
for more information.
--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 set-
tings. 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|--force ...
Override various checks, confirmations and protections. Use
with extreme caution.
-h|--help
Display help text.
--lockopt String
Used to pass options for special cases to lvmlockd. See lvm-
lockd(8) for more information.
--longhelp
Display long help text.
--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 --ver-
bose. Repeat once to also suppress any prompts with answer
'no'.
--reportformat basic|json
Overrides current output format for reports which is defined
globally by the report/output_format setting in lvm.conf. basic
is the original format with columns and rows. If there is more
than one report per command, each report is prefixed with the
report name for identification. json produces report output in
JSON format. See lvmreport(7) for more information.
-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 un-
usual 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 de-
tail 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 con-
tent.
Size[UNIT]
Size is an input number that accepts an optional unit. Input
units are always treated as base two values, regardless of capi-
talization, e.g. 'k' and 'K' both refer to 1024. The default
input unit is specified by letter, followed by |UNIT. UNIT rep-
resents 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
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.
EXAMPLES
Rename VG "vg02" to "myvg":
vgrename vg02 myvg
Rename the VG with the specified UUID to "myvg".
vgrename Zvlifi-Ep3t-e0Ng-U42h-o0ye-KHu1-nl7Ns4 myvg
