LVREMOVE(8)                 System Manager's Manual                LVREMOVE(8)

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  confirma-
       tion, 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 sec-
       ond time, with the hyphen, to remove the record of the former  LV  com-
       pletely.

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 set-
              tings.  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 lvm-
              lockd(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.
       --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 --ver-
              bose.  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 addi-
              tional "selected" field (-o selected) showing 1 if the row
              matches the selection and 0 otherwise.  For non-reporting com-
              mands 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 posi-
              tional 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 con-
              tent.
       Size[UNIT]
              Size  is  an  input number that accepts an optional unit.  Input
              units are always treated as base two values, regardless of capi-
              talization,  e.g.  'k'  and 'K' both refer to 1024.  The default
              input unit is specified by letter, followed by |UNIT.  UNIT rep-
              resents  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
