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).

Export specified VGs.

OPTIONS

The command profile to use for command configuration.
    See lvm.conf(5) for more information about profiles.

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.

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).

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.

A file listing devices that LVM should use.
    The file must exist in /data/data/com.termux/files/usr/etc/lvm/devices/ and is managed with the lvmdevices(8) command. This overrides the lvm.conf(5) devices/devicesfile and devices/use_devicesfile settings.

If set to no, the command will not attempt to use device-mapper.
    For testing and debugging.

Display help text.

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.

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

Display long help text.

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.

Disable locking. Use with caution, concurrent commands may produce
    incorrect results.

Persistent Reservation operation.
    start: register local key and acquire reservation. stop: unregister local key, releasing reservation. remove: preempt and abort another key. clear: remove reservation and keys. check: check if started. autostart: start if the VG autostart flag is set. lvmlocal.conf pr_key or host_id must be configured to use PR. For local VGs, Write Exclusive (WE) is used, and for shared VGs Write Exclusive, all registrants (WEAR) is used. Use --setpersist to automate and/or require PR.

An alias for --commandprofile or --metadataprofile, depending
    on the command.

Suppress output and log messages. Overrides --debug and --verbose.
    Repeat once to also suppress any prompts with answer 'no'.

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. json_std produces report output in JSON format which is more compliant with JSON standard. See lvmreport(7) for more information.

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.

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.

Set verbose level. Repeat from 1 to 4 times to increase the detail
    of messages sent to stdout and stderr.

Display version information.

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.
