+.TH VGEXPORT 8 "LVM TOOLS #VERSION#" "Red Hat, Inc."
+.
+.SH NAME
+.
+vgexport \(em Unregister volume group(s) from the system
+.
+.SH SYNOPSIS
+.
+\fBvgexport\fP \fIoption_args\fP \fIposition_args\fP
+.br
+ [ \fIoption_args\fP ]
+.br
+.
+.SH 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 \fBvgimport\fP(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.
+.P
+A VG cannot be exported until all of its LVs are inactive.
+.P
+LVM commands will ignore an exported VG or report an error if a command
+tries to use it.
+.P
+For an exported VG, the vgs command will display \"x\" in the third VG
+attribute, and the pvs command will display \"x\" in the second PV
+attribute. Both vgs and pvs will display \"exported\" from the export
+report field.
+.P
+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).
+.
+.SH USAGE
+.
+Export specified VGs.

+.SH OPTIONS
+.
+.
+.HP
+\fB-a\fP|\fB--all\fP
+.br
+.
+.HP
+\fB--commandprofile\fP \fIString\fP
+.br
+The command profile to use for command configuration.
+See \fBlvm.conf\fP(5) for more information about profiles.
+.
+.HP
+\fB--config\fP \fIString\fP
+.br
+Config settings for the command. These override \fBlvm.conf\fP(5) settings.
+The String arg uses the same format as \fBlvm.conf\fP(5),
+or may use section/field syntax.
+See \fBlvm.conf\fP(5) for more information about config.
+.
+.HP
+\fB-d\fP|\fB--debug\fP ...
+.br
+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).
+.
+.HP
+\fB--devices\fP \fIPV\fP
+.br
+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.
+.
+.HP
+\fB--devicesfile\fP \fIString\fP
+.br
+A file listing devices that LVM should use.
+The file must exist in \fI#DEFAULT_SYS_DIR#/devices/\fP and is managed
+with the \fBlvmdevices\fP(8) command.
+This overrides the \fBlvm.conf\fP(5) \fBdevices/devicesfile\fP and
+\fBdevices/use_devicesfile\fP settings.
+.
+.HP
+\fB--driverloaded\fP \fBy\fP|\fBn\fP
+.br
+If set to no, the command will not attempt to use device-mapper.
+For testing and debugging.
+.
+.HP
+\fB-h\fP|\fB--help\fP
+.br
+Display help text.
+.
+.HP
+\fB--journal\fP \fIString\fP
+.br
+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.
+.
+.HP
+\fB--lockopt\fP \fIString\fP
+.br
+Used to pass options for special cases to lvmlockd.
+See \fBlvmlockd\fP(8) for more information.
+.
+.HP
+\fB--longhelp\fP
+.br
+Display long help text.
+.
+.HP
+\fB--nohints\fP
+.br
+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.
+.
+.HP
+\fB--nolocking\fP
+.br
+Disable locking. Use with caution, concurrent commands may produce
+incorrect results.
+.
+.HP
+\fB--profile\fP \fIString\fP
+.br
+An alias for --commandprofile or --metadataprofile, depending
+on the command.
+.
+.HP
+\fB-q\fP|\fB--quiet\fP ...
+.br
+Suppress output and log messages. Overrides --debug and --verbose.
+Repeat once to also suppress any prompts with answer 'no'.
+.
+.HP
+\fB--reportformat\fP \fBbasic\fP|\fBjson\fP|\fBjson_std\fP
+.br
+Overrides current output format for reports which is defined globally by
+the report/output_format setting in \fBlvm.conf\fP(5).
+\fBbasic\fP 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. \fBjson\fP produces report
+output in JSON format. \fBjson_std\fP produces report output in
+JSON format which is more compliant with JSON standard.
+See \fBlvmreport\fP(7) for more information.
+.
+.HP
+\fB-S\fP|\fB--select\fP \fIString\fP
+.br
+Select objects for processing and reporting based on specified criteria.
+The criteria syntax is described by \fB--select help\fP and \fBlvmreport\fP(7).
+For reporting commands, one row is displayed for each object matching the criteria.
+See \fB--options help\fP 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.
+.
+.HP
+\fB-t\fP|\fB--test\fP
+.br
+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.
+.
+.HP
+\fB-v\fP|\fB--verbose\fP ...
+.br
+Set verbose level. Repeat from 1 to 4 times to increase the detail
+of messages sent to stdout and stderr.
+.
+.HP
+\fB--version\fP
+.br
+Display version information.
+.
+.HP
+\fB-y\fP|\fB--yes\fP
+.br
+Do not prompt for confirmation interactively but always assume the
+answer yes. Use with extreme caution.
+(For automatic no, see -qq.)
+.
+.SH VARIABLES
+.
+.TP
+.I VG
+Volume Group name. See \fBlvm\fP(8) for valid names.
+.TP
+.I Tag
+Tag name. See \fBlvm\fP(8) for information about tag names and using tags
+in place of a VG, LV or PV.
+.TP
+.I Select
+Select indicates that a required positional parameter can
+be omitted if the \fB--select\fP option is used.
+No arg appears in this position.
+.TP
+.I String
+See the option description for information about the string content.
+.TP
+.IR 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:
+.BR b | B
+is bytes,
+.BR s | S
+is sectors of 512 bytes,
+.BR k | K
+is KiB,
+.BR m | M
+is MiB,
+.BR g | G
+is GiB,
+.BR t | T
+is TiB,
+.BR p | P
+is PiB,
+.BR e | E
+is EiB.
+(This should not be confused with the output control --units, where
+capital letters mean multiple of 1000.)
+.
+.SH ENVIRONMENT VARIABLES
+.
+See \fBlvm\fP(8) for information about environment variables used by lvm.
+For example, LVM_VG_NAME can generally be substituted for a required VG parameter.
