--aligned
Use with --separator to align the output columns
-a|--all
Show information about devices that have not been initial‐
ized by LVM, i.e. they are not PVs.
--binary
Use binary values "0" or "1" instead of descriptive liter‐
al 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
Devices that the command can use. This option can be re‐
peated 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) de‐
vices/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.
-h|--help
Display help text.
--ignorelockingfailure
Allows a command to continue with read-only metadata oper‐
ations after locking failures.
--journal String
Record information in the systemd journal. This informa‐
tion 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.
--nosuffix
Suppress the suffix on output sizes. Use with --units (ex‐
cept 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 de‐
fault fields, - will remove the specified fields from the
default fields, and # will compact specified fields (re‐
moving 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 op‐
tion: -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 con‐
fig options. See lvmreport(7) for more information about
reporting.
--profile String
An alias for --commandprofile or --metadataprofile, de‐
pending 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 at‐
tempt 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 de‐
fined 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 identifi‐
cation. json produces report output in JSON format. See
lvmreport(7) for more information.
--rows
Output columns as rows.
--segments
Produces one line of output for each contiguous allocation
of space on each PV, showing the start (pvseg_start) and
length (pvseg_size) in units of physical extents.
-S|--select String
Select objects for processing and reporting based on spec‐
ified criteria. The criteria syntax is described by --se‐
lect 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 se‐
lected) 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. Re‐
places 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 nev‐
ertheless returning success to the calling function. This
may lead to unusual error messages in multi-stage opera‐
tions if a tool relies on reading back metadata it be‐
lieves 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)ec‐
tors, (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 speci‐
fied, 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 au‐
tomatic no, see -qq.)
PV Physical Volume name, a device path under /dev. For com‐
mands managing physical extents, a PV positional arg gen‐
erally accepts a suffix indicating a range (or multiple
ranges) of physical extents (PEs). When the first PE is
omitted, it defaults to the start of the device, and when
the last PE is omitted it defaults to end. Start and end
range (inclusive): PV[:PE-PE]... Start and length range
(counting from 0): PV[:PE+PE]...
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, regard‐
less of capitalization, e.g. 'k' and 'K' both refer to
1024. The default input unit is specified by letter, fol‐
lowed 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 con‐
trol --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.
The pv_attr bits are:
1 (d)uplicate, (a)llocatable, (u)sed
2 e(x)ported
3 (m)issing
