LVDISPLAY(8) System Manager's Manual LVDISPLAY(8)
lvdisplay - Display information about a logical volume
lvdisplay
[ option_args ]
[ position_args ]
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.

[ -q|--quiet ]
[ -t|--test ]

[ -y|--yes ]

--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
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.
--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).
--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
metadata/record_lvs_history was enabled.
--ignorelockingfailure
Allows a command to continue with read-only metadata
operations after locking failures.
--ignoreskippedcluster
Use to avoid exiting with an non-zero status code if the
command is run without clustered locking and clustered VGs are
skipped.
--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.
--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 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. It can also be
used to peek inside the metadata of clustered VGs when
clustered locking is not configured or 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.
--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.
--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 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.)
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: 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.)
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.
