NAME¶

lvremove — Remove logical volume(s) from the system

SYNOPSIS¶

lvremove position_args
[ option_args ]

DESCRIPTION¶

lvremove removes one or more LVs. For standard LVs, this returns the logical extents that were used by the LV to the VG for use by other LVs.

Confirmation will be requested before deactivating any active LV prior to removal. LVs cannot be deactivated or removed while they are open (e.g. if they contain a mounted filesystem). Removing an origin LV will also remove all dependent snapshots.

When a single force option is used, LVs are removed without confirmation, and the command will try to deactivate unused LVs.

To remove damaged LVs, two force options may be required (-ff).

Historical LVs

If the configuration setting metadata/record_lvs_history is enabled and the LV being removed forms part of the history of at least one LV that is still present, then a simplified representation of the LV will be retained. This includes the time of removal (lv_time_removed reporting field), creation time (lv_time), name (lv_name), LV uuid (lv_uuid) and VG name (vg_name). This allows later reporting to see the ancestry chain of thin snapshot volumes, even after some intermediate LVs have been removed. The names of such historical LVs acquire a hyphen as a prefix (e.g. '-lvol1') and cannot be reactivated. Use lvremove a second time, with the hyphen, to remove the record of the former LV completely.

USAGE¶

lvremove VG|LV|Tag|Select ...

Common options for lvm:

OPTIONS¶

-A|--autobackup y|n
Specifies if metadata should be backed up automatically after a change. Enabling this is strongly advised! See vgcfgbackup(8) for more information.

--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.

-f|--force ...
Override various checks, confirmations and protections. Use with extreme caution.

-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.

--nohistory
Do not record history of LVs being removed. This has no effect unless the configuration setting metadata/record_lvs_history is enabled.

--nolocking
Disable locking.

--noudevsync
Disables udev synchronisation. The process will not wait for notification from udev. It will continue irrespective of any possible udev processing in the background. Only use this if udev is not running or has rules that ignore the devices LVM creates.

--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.

LV

Logical Volume name. See lvm(8) for valid names. An LV positional arg generally includes the VG name and LV name, e.g. VG/LV.

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.

EXAMPLES¶

Remove an active LV without asking for confirmation.
lvremove -f vg00/lvol1

Remove all LVs the specified VG.
lvremove vg00
