OPTIONS¶
--aligned
Use with --separator to align the output columns
-a|--all
List all VGs. Equivalent to not specifying any VGs.
--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(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.
--headings
none|abbrev|full|0|1|2
Type of headings to use in report output. none or 0: No
headings. abbrev or 1: Column name abbreviations. full
or 2: Full column names.
-h|--help
Display help text.
--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.
--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.
--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
Prevent the command from making changes, including activation and metadata
updates. (See --permission r for read only LVs.)
--reportformat basic|json|json_std
Overrides current output format for reports which is defined globally by the
report/output_format setting in lvm.conf(5). 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. json_std produces
report output in JSON format which is more compliant with JSON standard. See
lvmreport(7) for more information.
--rows
Output columns as rows.
-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.
--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.)
VARIABLES¶
- VG
- Volume Group name. See lvm(8) for valid names.
- 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.
NOTES¶
The vg_attr bits are:
- 1
- Permissions: (w)riteable, (r)ead-only
- 2
- Resi(z)eable
- 3
- E(x)ported
- 4
- (p)artial: one or more physical volumes belonging to the volume group are missing from the system
- 5
- Allocation policy: (c)ontiguous, c(l)ing, (n)ormal, (a)nywhere
- 6
- (c)lustered, (s)hared
