--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 acces‐sible, 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 morecontrol 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

The command profile to use for command configuration. See lvm.conf(5) for more information about profiles.

--config

Config settings for the command. These override lvm.conf settings. The String arg uses the same format as lvm.conf, or mayuse section/field syntax. See lvm.conf(5) for more information about config.

--configreport

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 config‐ured).

--driverloaded

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_historywas 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 areskipped.

--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

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

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 # willcompact specified fields (removing them when empty for all rows.) Use -o help to view the list of all available fields. Useseparate 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 allPV fields, pvseg_all all PV segment fields, seg_all all LV segment fields, and pvseg_all all PV segment columns. See thelvm.conf report section for more config options. See lvmreport(7) for more information about reporting.

--profile

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 beused to peek inside metadata used by a virtual machine image while the virtual machine is running. It can also be used topeek inside the metadata of clustered VGs when clustered locking is not configured or running. No attempt will be made to com‐municate with the device-mapper kernel driver, so this option is unable to report whether or not LVs are actually in use.

--reportformat

Overrides current output format for reports which is defined globally by the report/output_format setting in lvm.conf. basicis the original format with columns and rows. If there is more than one report per command, each report is prefixed with thereport name for identification. json produces report output in JSON format. See lvmreport(7) for more information.

-S|--select

Select objects for processing and reporting based on specified criteria. The criteria syntax is described by --select helpand lvmreport(7). For reporting commands, one row is displayed for each object matching the criteria. See --options help forselectable object fields. Rows can be displayed with an additional "selected" field (-o selected) showing 1 if the rowmatches the selection and 0 otherwise. For non-reporting commands which process LVM entities, the selection is used to chooseitems to process.

--separator

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) formore information about shared VGs.

-O|--sort

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

-t|--test

Run in test mode. Commands will not update metadata. This is implemented by disabling all metadata writing but neverthelessreturning success to the calling function. This may lead to unusual error messages in multi-stage operations if a tool relieson reading back metadata it believes has changed but hasn't.

--unbuffered

Produce output immediately without sorting or aligning the columns properly.

--units

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.)VARIABLESVGVolume Group name. See lvm(8) for valid names.LVLogical Volume name. See lvm(8) for valid names. An LV positional arg generally includes the VG name and LV name, e.g.VG/LV.TagTag name. See lvm(8) for information about tag names and using tags in place of a VG, LV or PV.StringSee 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 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 ismegabytes, g|G is gigabytes, t|T is terabytes, p|P is petabytes, e|E is exabytes. (This should not be confused with the out‐put control --units, where capital letters mean multiple of 1000.)ENVIRONMENT VARIABLESSee lvm(8) for information about environment variables used by lvm. For example, LVM_VG_NAME can generally be substituted for arequired VG parameter.
