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
       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.

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 ]
           [    --longhelp ]
           [    --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 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|--force ...
              Override various checks, confirmations and protections.  Use with extreme caution.

       -h|--help
              Display help text.

       --longhelp
              Display long help text.

       --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'.

       --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
              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.)

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
