lvs - Display information about logical volumes
lvs
[ option_args ]
[ position_args ]
lvs produces formatted output about LVs.
lvs
Common options for lvm:
--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).
--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.
--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.
--nameprefixes
Add an "LVM2_" prefix plus the field name to the output. Useful with
--noheadings to produce a list of field=value pairs that can be used to set
environment variables (for example, in udev rules).
--noheadings
Suppress the headings line that is normally the first line of output. Useful
if grepping the output.
--nolocking
Disable locking.
--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. 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.
--rows
Output columns as rows.
--segments
Use default columns that emphasize segment 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.
--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.
--trustcache
Avoids certain device scanning during command processing. Do not use.
--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.
--unquoted
When used with --nameprefixes, output values in the field=value pairs are not
quoted.
-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.
