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.
