.SH DESCRIPTION
|
|
.
|
|
vgrename renames a VG.
|
|
.P
|
|
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 filters 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 correctly. When
|
|
two VGs have the same name, the VG UUID can be used in place of the source
|
|
VG name.
|
|
.
|
|
.SH USAGE
|

\fB-A\fP|\fB--autobackup\fP \fBy\fP|\fBn\fP
|
|
.br
|
|
Specifies if metadata should be backed up automatically after a change.
|
|
Enabling this is strongly advised! See \fBvgcfgbackup\fP(8) for more information.
|
|
.
|
|
.HP
|
|
\fB--commandprofile\fP \fIString\fP
|
|
.br
|
|
The command profile to use for command configuration.
|
|
See \fBlvm.conf\fP(5) for more information about profiles.
|
|
.
|
|
.HP
|
|
\fB--config\fP \fIString\fP
|
|
.br
|
|
Config settings for the command. These override \fBlvm.conf\fP(5) settings.
|
|
The String arg uses the same format as \fBlvm.conf\fP(5),
|
|
or may use section/field syntax.
|
|
See \fBlvm.conf\fP(5) for more information about config.
|
|
.
|
|
.HP
|
|
\fB-d\fP|\fB--debug\fP ...
|
|
.br
|
|
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).
|
|
.
|
|
.HP
|
|
\fB--devices\fP \fIPV\fP
|
|
.br
|
|
Restricts the devices that are visible and accessible to the command.
|
|
Devices not listed will appear to be missing. This option can be
|
|
repeated, or accepts a comma separated list of devices. This overrides
|
|
the devices file.
|
|
.
|
|
.HP
|
|
\fB--devicesfile\fP \fIString\fP
|
|
.br
|
|
A file listing devices that LVM should use.
|
|
The file must exist in \fI#DEFAULT_SYS_DIR#/devices/\fP and is managed
|
|
with the \fBlvmdevices\fP(8) command.
|
|
This overrides the \fBlvm.conf\fP(5) \fBdevices/devicesfile\fP and
|
|
\fBdevices/use_devicesfile\fP settings.
|
|
.
|
|
.HP
|
|
\fB--driverloaded\fP \fBy\fP|\fBn\fP
|

|
|

|
|
For testing and debugging.
|
|
.
|
|
.HP
|
|
\fB-f\fP|\fB--force\fP ...
|
|

|
|
Override various checks, confirmations and protections.
|
|
Use with extreme caution.
|
|
.
|
|
.HP
|
|
\fB-h\fP|\fB--help\fP
|
|

|
|
Display help text.
|
|
.
|
|
.HP
|
|
\fB--journal\fP \fIString\fP
|
|
.br
|
|

|
|

|
|
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.
|
|
.
|
|
.HP
|
|
\fB--lockopt\fP \fIString\fP

|
|
.HP
|
|

|
|
.br
|
|

|
|
.
|
|
.HP
|
|
\fB--nohints\fP
|
|
.br
|
|
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.
|
|
.
|
|
.HP
|
|
\fB--nolocking\fP
|
|
.br
|
|
Disable locking. Use with caution, concurrent commands may produce
|
|
incorrect results.
|
|
.
|
|
.HP
|
|
\fB--profile\fP \fIString\fP
|
|
.br
|
|

Suppress output and log messages. Overrides --debug and --verbose.

Repeat once to also suppress any prompts with answer 'no'.
|
|
.
|
|
.HP
|
|
\fB--reportformat\fP \fBbasic\fP|\fBjson\fP|\fBjson_std\fP
|
|
.br
|
|
Overrides current output format for reports which is defined globally by
|
|
the report/output_format setting in \fBlvm.conf\fP(5).
|
|
\fBbasic\fP 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. \fBjson\fP produces report
|
|
output in JSON format. \fBjson_std\fP produces report output in
|
|
JSON format which is more compliant with JSON standard.

|
|
.HP
|
|
\fB-t\fP|\fB--test\fP
|
|
.br
|
|
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.
|
|
.
|
|
.HP
|
|

|
|
.HP
|
|
\fB-y\fP|\fB--yes\fP
|
|
.br
|
|
Do not prompt for confirmation interactively but always assume the
|
|
answer yes. Use with extreme caution.
|
|
(For automatic no, see -qq.)
|

.SH VARIABLES

|
|
Volume Group name. See \fBlvm\fP(8) for valid names.

.IR 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:
|
|
.BR b | B
|
|
is bytes,
|
|
.BR s | S
|
|
is sectors of 512 bytes,
|
|
.BR k | K
|
|
is KiB,
|
|
.BR m | M
|
|
is MiB,
|

is TiB,
|
|
.BR p | P
|
|
is PiB,
|

(This should not be confused with the output control --units, where
|
|
capital letters mean multiple of 1000.)

.SH ENVIRONMENT VARIABLES
|
|
.
|
|
See \fBlvm\fP(8) for information about environment variables used by lvm.
|
