.TH VGEXPORT 8 "LVM TOOLS #VERSION#" "Red Hat, Inc."
.SH NAME
vgexport - 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 makes inactive VGs unknown to the system. In this state, all the
PVs in the VG can be moved to a different system, from which
\fBvgimport\fP(8) can then be run.

Most LVM tools ignore exported VGs.

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
.ad l
\fB-a\fP|\fB--all\fP
.br
.ad b
.HP
.ad l
\fB--commandprofile\fP \fIString\fP
.br
The command profile to use for command configuration.
See \fBlvm.conf\fP(5) for more information about profiles.
.ad b
.HP
.ad l
\fB--config\fP \fIString\fP
.br
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 \fBlvm.conf\fP(5) for more information about config.
.ad b
.HP
.ad l
\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).
.ad b
.HP
.ad l
\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.
.ad b
.HP
.ad l
\fB-h\fP|\fB--help\fP
.br
Display help text.
.ad b
.HP
.ad l
\fB--lockopt\fP \fIString\fP
.br
Used to pass options for special cases to lvmlockd.
See \fBlvmlockd\fP(8) for more information.
.ad b
.HP
.ad l
\fB--longhelp\fP
.br
Display long help text.
.ad b
.HP
.ad l
\fB--profile\fP \fIString\fP
.br
An alias for --commandprofile or --metadataprofile, depending
on the command.
.ad b
.HP
.ad l
\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'.
.ad b
.HP
.ad l
\fB--reportformat\fP \fBbasic\fP|\fBjson\fP
.br
Overrides current output format for reports which is defined globally by
the report/output_format setting in lvm.conf.
\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. See \fBlvmreport\fP(7) for more information.
.ad b
.HP
.ad l
\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.
.ad b
.HP
.ad l
\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.
.ad b
.HP
.ad l
\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.
.ad b
.HP
.ad l
\fB--version\fP
.br
Display version information.
.ad b
.HP
.ad l
\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.)
.ad b
.SH VARIABLES
.HP
\fIVG\fP
.br
Volume Group name.  See \fBlvm\fP(8) for valid names.
.HP
\fITag\fP
.br
Tag name.  See \fBlvm\fP(8) for information about tag names and using tags
in place of a VG, LV or PV.
.HP
\fISelect\fP
.br
Select indicates that a required positional parameter can
be omitted if the \fB--select\fP option is used.
No arg appears in this position.
.HP
\fIString\fP
.br
See the option description for information about the string content.
.HP
\fISize\fP[UNIT]
.br
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: \fBbBsSkKmMgGtTpPeE\fP.
b|B is bytes, s|S is sectors of 512 bytes, k|K is kilobytes,
m|M is megabytes, g|G is gigabytes, t|T is terabytes,
p|P is petabytes, e|E is exabytes.
(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.
