Ubuntu Manpage: lvremove - Remove logical volume(s) from the system

Provided by: lvm2_2.03.11-2.1ubuntu4_amd64

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.

           [    --nolocking ]
           [    --profile String ]
           [    --version ]

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 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.

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

-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.

--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. 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: 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.

EXAMPLES

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

       Remove all LVs the specified VG.
       lvremove vg00
