VGRENAME(8)              System Manager's Manual             VGRENAME(8)

NAME         top

       vgrename — Rename a volume group

SYNOPSIS         top

       vgrename position_args
           [ option_args ]

DESCRIPTION         top

       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         top

OPTIONS         top


       -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(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
              Devices  that  the  command  can  use.  This option can be
              repeated or accepts a comma  separated  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)
              devices/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 debugging.

       -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 information 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 information.

       --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.

       --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(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 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         top

       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         top

       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         top

       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
