NAME

       lvdisplay — Display information about a logical volume

SYNOPSIS

       lvdisplay
           [ option_args ]
           [ position_args ]

DESCRIPTION

       lvdisplay shows the attributes of LVs, like size, read/write status, snapshot information,
       etc.

       lvs(8) is a preferred alternative that shows the same information and more, using  a  more
       compact and configurable output format.

OPTIONS

       --aligned
              Use with --separator to align the output columns

       -a|--all
              Show  information  about internal LVs.  These are components of normal LVs, such as
              mirrors, which are not independently accessible, e.g. not mountable.

       --binary
              Use binary values "0" or "1" instead of descriptive literal values for columns that
              have  exactly  two  valid  values to report (not counting the "unknown" value which
              denotes that the value could not be determined).

       -c|--colon
              Generate colon separated output for easier parsing in scripts  or  programs.   Also
              see vgs(8) which provides considerably more control over the output.

       -C|--columns
              Display  output  in columns, the equivalent of vgs(8).  Options listed are the same
              as options given in vgs(8).

       --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.

       --configreport log|vg|lv|pv|pvseg|seg
              See lvmreport(7).

       -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.

       --foreign
              Report/display foreign VGs that would otherwise be skipped.  See lvmsystemid(7) for
              more information about foreign VGs.

       -h|--help
              Display help text.

       -H|--history
              Include historical LVs in the output.  (This has no effect unless LVs were  removed
              while lvm.conf(5) metadata/record_lvs_history was enabled.

       --ignorelockingfailure
              Allows  a  command  to  continue  with  read-only metadata operations after locking
              failures.

       --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.

       --logonly
              Suppress command report and display only log report.

       --longhelp
              Display long help text.

       -m|--maps
              Display the mapping of logical  extents  to  PVs  and  physical  extents.   To  map
              physical     extents     to     logical     extents     use:     pvs     --segments
              -o+lv_name,seg_start_pe,segtype

       --noheadings
              Suppress the headings line that is normally the first line of  output.   Useful  if
              grepping the output.

       --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.

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

       --nosuffix
              Suppress the suffix on  output  sizes.  Use  with  --units  (except  h  and  H)  if
              processing the output.

       -o|--options String
              Comma-separated,  ordered  list of fields to display in columns.  String arg syntax
              is: [+|-|#]Field1[,Field2 ...]  The prefix + will append the  specified  fields  to
              the default fields, - will remove the specified fields from the default fields, and
              # will compact specified fields (removing them when empty for all  rows.)   Use  -o
              help  to  view  the  list of all available fields.  Use separate lists of fields to
              add,  remove  or   compact   by   repeating   the   -o   option:   -o+field1,field2
              -o-field3,field4  -o#field5.   These  lists  are evaluated from left to right.  Use
              field name lv_all to view all LV fields,  vg_all  all  VG  fields,  pv_all  all  PV
              fields,  pvseg_all  all  PV  segment  fields,  seg_all  all  LV segment fields, and
              pvseg_all all PV segment columns.  See the  lvm.conf(5)  report  section  for  more
              config options.  See lvmreport(7) for more information about reporting.

       --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'.

       --readonly
              Run the command in a special  read-only  mode  which  will  read  on-disk  metadata
              without needing to take any locks. This can be used to peek inside metadata used by
              a virtual machine image while the virtual machine is running. No  attempt  will  be
              made  to communicate with the device-mapper kernel driver, so this option is unable
              to report whether or not LVs are actually in use.

       --segments

       -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.

       --separator String
              String to use to separate each column. Useful if grepping the output.

       --shared
              Report/display shared VGs that would otherwise be  skipped  when  lvmlockd  is  not
              being used on the host.  See lvmlockd(8) for more information about shared VGs.

       -O|--sort String
              Comma-separated ordered list of columns to sort by. Replaces the default selection.
              Precede any column with - for a reverse sort on that column.

       -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.

       --unbuffered
              Produce output immediately without sorting or aligning the columns properly.

       --units [Number]r|R|h|H|b|B|s|S|k|K|m|M|g|G|t|T|p|P|e|E
              All  sizes are output in these units: human-(r)eadable with '<' rounding indicator,
              (h)uman-readable,  (b)ytes,  (s)ectors,  (k)ilobytes,   (m)egabytes,   (g)igabytes,
              (t)erabytes,  (p)etabytes,  (e)xabytes.  Capitalise to use multiples of 1000 (S.I.)
              instead of 1024.  Custom units can be specified, e.g. --units 3M.

       -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.

       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.
