NAME

       vgexport — Unregister volume group(s) from the system

SYNOPSIS

       vgexport option_args position_args
           [ option_args ]

DESCRIPTION

       vgexport changes a VG into the exported state, which ensures that the VG and its disks are
       not being used, and cannot be used until the VG is imported by vgimport(8).  Putting a  VG
       into  an  unusable, offline state can be useful when doing things like moving a VG's disks
       to  another  system.   Exporting  a  VG  provides  some  protection  from  its  LVs  being
       accidentally used, or being used by an automated system before it's ready.

       A VG cannot be exported until all of its LVs are inactive.

       LVM commands will ignore an exported VG or report an error if a command tries to use it.

       For  an  exported  VG,  the  vgs  command will display attribute, and the pvs command will
       display attribute.  Both vgs and pvs will display report field.

       vgexport clears the VG system ID, and vgimport sets the VG system ID  to  match  the  host
       running vgimport (if the host has a system ID).

       Export specified VGs.

OPTIONS

       -a|--all

       --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
              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.

       --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.

       -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. 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
              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.

       -S|--select String
              Select objects for processing and  reporting  based  on  specified  criteria.   The
              criteria  syntax  is  described  by  --select help and lvmreport(7).  For reporting
              commands, one row  is  displayed  for  each  object  matching  the  criteria.   See
              --options  help  for  selectable  object  fields.   Rows  can  be displayed with an
              additional "selected" field  (-o  selected)  showing  1  if  the  row  matches  the
              selection  and 0 otherwise.  For non-reporting commands which process LVM entities,
              the selection is used to choose items to process.

       -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.

       Tag    Tag  name.  See lvm(8) for information about tag names and using tags in place of a
              VG, LV or PV.

       Select Select indicates that a  required  positional  parameter  can  be  omitted  if  the
              --select option is used.  No arg appears in this position.

       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.
