VGEXPORT(8)    (LVM TOOLS 2.03.11(2) (2021-01-08))    VGEXPORT(8)

     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).

     USAGE
          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 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.

          -h|--help
               Display help text.

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

          --longhelp
               Display long help text.

          --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

     VGEXPORT(8)    (LVM TOOLS 2.03.11(2) (2021-01-08))    VGEXPORT(8)

               --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.

          -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: bBsSkKmMgGtTpPeE.  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.
