[ VG|Tag ... ]Common options for lvm:
[ -d|--debug ][ -h|--help ][ -q|--quiet ][ -t|--test ][ -v|--verbose ][ -y|--yes ][ --commandprofile String ][ --config String ][ --driverloaded y|n ][ --lockopt String ][ --longhelp ][ --profile String ][ --version ]
--alignedUse with --separator to align the output columns
-a|--allList all VGs. Equivalent to not specifying any VGs.
--binaryUse 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 StringThe command profile to use for command configuration. See lvm.conf(5) for more information about profiles.
--config StringConfig 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|segSee 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|nIf set to no, the command will not attempt to use device-mapper. For testing and debugging.
--foreignReport/display foreign VGs that would otherwise be skipped. See lvmsystemid(7) for more information about foreign VGs.
-h|--helpDisplay help text.
--ignorelockingfailureAllows a command to continue with read-only metadata operations after locking failures.
--ignoreskippedclusterUse to avoid exiting with an non-zero status code if the command is run without clustered locking and clustered VGs are skipped.
--lockopt StringUsed to pass options for special cases to lvmlockd. See lvmlockd(8) for more information.
--logonlySuppress command report and display only log report.
--longhelpDisplay long help text.
--nameprefixesAdd 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).
--noheadingsSuppress the headings line that is normally the first line of output. Useful if grepping the output.
--nosuffixSuppress the suffix on output sizes. Use with --units (except h and H) if processing the output.
-o|--options StringComma-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 StringAn 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'.
--readonlyRun 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|jsonOverrides 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.
--rowsOutput columns as rows.
-S|--select StringSelect 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 StringString to use to separate each column. Useful if grepping the output.
--sharedReport/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 StringComma-separated ordered list of columns to sort by. Replaces the default selection. Precede any column with - for a reverse sort on that column.
-t|--testRun 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.
--trustcacheAvoids certain device scanning during command processing. Do not use.
--unbufferedProduce 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|EAll 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.
--unquotedWhen 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.
--versionDisplay version information.
-y|--yesDo not prompt for confirmation interactively but always assume the answer yes. Use with extreme caution. (For automatic no, see -qq.)
VGVolume Group name. See lvm(8) for valid names.
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 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.)lvm(8) for information about environment variables used by lvm. For example, LVM_VG_NAME can generally be substituted for a required VG parameter.
- Permissions: (w)riteable, (r)ead-only
- (p)artial: one or more physical volumes belonging to the volume group are missing from the system
- Allocation policy: (c)ontiguous, c(l)ing, (n)ormal, (a)nywhere
- (c)lustered, (s)hared
