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 val-
ues 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 pvs(8) which provides considerably more con-
trol over the output. The values are:
• physical volume device name
• volume group name
• physical volume size in sectors
• internal physical volume number (obsolete)
• physical volume status
• physical volume (not) allocatable
• current number of logical volumes on this physical volume
• physical extent size in kilobytes
• total number of physical extents
• free number of physical extents
• allocated number of physical extents
-C|--columns
Display output in columns. The equivalent of pvs(8). Options
listed are the same as options given in pvs(8).
--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) set-
tings. The String arg uses the same format as lvm.conf(5), or
may use section/field syntax. See lvm.conf(5) for more informa-
tion 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 com-
mand. 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) com-
mand. This overrides the lvm.conf(5) devices/devicesfile and de-
vices/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 head-
ings. 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 lvm-
lockd(8) for more information.
--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 ex-
tents.
--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 pro-
duce 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 sepa-
rate 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 in-
formation about reporting.
--profile String
An alias for --commandprofile or --metadataprofile, depending on
the command.
-q|--quiet ...
Suppress output and log messages. Overrides --debug and --ver-
bose. 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). ba-
sic 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.
--segments
-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 selec-
table 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.
-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 im-
plemented by disabling all metadata writing but nevertheless re-
turning 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 de-
tail 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 extents, a PV positional arg generally accepts
a suffix indicating a range (or multiple ranges) of physical ex-
tents (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 con-
tent.
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 in-
put unit is specified by letter, followed by |UNIT. UNIT repre-
sents 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 pa-
rameter.
