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.

       Common options for lvm:
           [ -d|--debug ]
           [ -h|--help ]
           [ -q|--quiet ]

           [    --longhelp ]
           [    --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.

       --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.

       --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 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.)

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
