PVDISPLAY(8) System Manager's Manual PVDISPLAY(8)
NAME
pvdisplay - Display various attributes of physical volume(s)
SYNOPSIS
pvdisplay
[ option_args ]
[ position_args ]
DESCRIPTION
pvdisplay shows the attributes of PVs, like size, physical extent size, space used for the
VG descriptor area, etc.
pvs(8) is a preferred alternative that shows the same information and more, using a more
compact and configurable output format.

OPTIONS
--aligned
Use with --separator to align the output columns
-a|--all
Show information about devices that have not been initialized by LVM, i.e. they are
not PVs.
--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 de-
notes 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 more control 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 String
The command profile to use for command configuration. See lvm.conf(5) for more in-
formation 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.
--ignorelockingfailure
Allows a command to continue with read-only metadata operations after locking fail-
ures.
--lockopt String
Used to pass options for special cases to lvmlockd. See lvmlockd(8) for more in-
formation.
--logonly
Suppress command report and display only log report.
--longhelp
Display long help text.
-m|--maps
Display the mapping of physical extents to LVs and logical extents.
--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 process-
ing 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 with-
out 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 re-
port/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 for-
mat. See lvmreport(7) for more information.
-S|--select String
Select objects for processing and reporting based on specified criteria. The cri-
teria syntax is described by --select help and lvmreport(7). For reporting com-
mands, one row is displayed for each object matching the criteria. See --options
help for selectable object fields. Rows can be displayed with an additional "se-
lected" field (-o selected) showing 1 if the row matches the selection and 0 other-
wise. 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 be-
ing used on the host. See lvmlockd(8) for more information about shared VGs.
-s|--short
Only display the size of the given PVs.
-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 dis-
abling all metadata writing but nevertheless returning success to the calling func-
tion. 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 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)er-
abytes, (p)etabytes, (e)xabytes. Capitalise to use multiples of 1000 (S.I.) in-
stead 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.)
VARIABLES
PV
Physical Volume name, a device path under /dev. For commands managing physical ex-
tents, a PV positional arg generally accepts a suffix indicating a range (or multi-
ple 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, regardless of capitalization, e.g. 'k' and 'K' both re-
fer 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 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.
