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 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

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 infor‐
              mation about profiles.

       --config String
              Config settings for the command. These override lvm.conf(5) settings.  The String  arg
              uses the same format as lvm.conf(5), 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).

       --devices PV
              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 sep‐
              arated list of devices. This overrides the devices file.

       --devicesfile String
              A  file listing devices that LVM should use.  The file must exist in /etc/lvm/devices/
              and is managed with the lvmdevices(8) command.  This  overrides  the  lvm.conf(5)  de‐
              vices/devicesfile and devices/use_devicesfile settings.

       --driverloaded y|n
              If  set to no, the command will not attempt to use device-mapper.  For testing and de‐
              bugging.

       -f|--force ...
              Override various checks, confirmations and protections.  Use with extreme caution.

       -h|--help
              Display help text.

       --journal String
              Record information in the systemd journal.  This information is in addition to  infor‐
              mation 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.

       --lockopt String
              Used to pass options for special cases to lvmlockd.  See lvmlockd(8) for more informa‐
              tion.

       --longhelp
              Display long help text.

       --nohints
              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.

       --nolocking
              Disable  locking. Use with caution, concurrent commands may produce incorrect results.


       --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 re‐
              port/output_format setting in lvm.conf(5).  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 read‐
              ing 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: b|B is bytes, s|S is sectors of 512 bytes, k|K is KiB, m|M
              is MiB, g|G is GiB, t|T is TiB, p|P is PiB, e|E is EiB.  (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
