pvdisplay shows the attributes of PVs, like size, physical extent size,

space used for the VG descriptor area, etc.
|
|
.P
|
|
\fBpvs\fP(8) is a preferred alternative that shows the same information
|
|
and more, using a more compact and configurable output format.

|
\fB--devices\fP \fIPV\fP
|

|
|
.
|
|
.HP
|
|
\fB--lockopt\fP \fIString\fP
|
|

Suppress the headings line that is normally the first line of output.
|
|
Useful if grepping the output.
|
|
.
|
|
.HP
|
|
\fB--nohints\fP
|
|
.br
|
|
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.
|
|
.
|
|
.HP
|
|
\fB--nolocking\fP
|
|
.br
|

|
|
\fB-o\fP|\fB--options\fP \fIString\fP
|
|
.br
|
|
Comma-separated, ordered list of fields to display in columns.
|
|
String arg syntax is: [\fB+\fP|\fB-\fP|\fB#\fP]\fIField1\fP[\fB,\fP\fIField2\fP ...]
|
|
The prefix \fB+\fP will append the specified fields to the default fields,
|
|
\fB-\fP will remove the specified fields from the default fields, and
|
|
\fB#\fP will compact specified fields (removing them when empty for all rows.)
|
|
Use \fB-o help\fP 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 \fBlv_all\fP to view all LV fields,
|
|
\fBvg_all\fP all VG fields,
|
|
\fBpv_all\fP all PV fields,
|
|
\fBpvseg_all\fP all PV segment fields,
|
|
\fBseg_all\fP all LV segment fields, and
|
|
\fBpvseg_all\fP all PV segment columns.

.HP
|
|
\fB--profile\fP \fIString\fP
|
|
.br
|
|

|
|
on the command.
|
|
.
|
|
.HP
|
|
\fB-q\fP|\fB--quiet\fP ...
|
|
.br
|
|
Suppress output and log messages. Overrides --debug and --verbose.
|
|
Repeat once to also suppress any prompts with answer 'no'.
|
|
.
|
|
.HP
|
|
\fB--readonly\fP
|
|
.br
|
|
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 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.
|
|
.
|
|
.HP
|
|
\fB--reportformat\fP \fBbasic\fP|\fBjson\fP
|
|
.br
|
|
Overrides current output format for reports which is defined globally by
|
|
the report/output_format setting in \fBlvm.conf\fP(5).
|
|
\fBbasic\fP 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. \fBjson\fP produces report
|
|
output in JSON format. See \fBlvmreport\fP(7) for more information.
|
|
.
|
|
.HP
|
|
\fB-S\fP|\fB--select\fP \fIString\fP
|
|
.br
|
|
Select objects for processing and reporting based on specified criteria.
|
|
The criteria syntax is described by \fB--select help\fP and \fBlvmreport\fP(7).
|
|
For reporting commands, one row is displayed for each object matching the criteria.
|
|
See \fB--options help\fP 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.
|
|
.
|
|
.HP
|
|
\fB--separator\fP \fIString\fP
|
|
.br
|
|
String to use to separate each column. Useful if grepping the output.
|
|
.
|
|
.HP
|
|
\fB--shared\fP
|
|
.br
|
|
Report/display shared VGs that would otherwise be skipped when
|
|
lvmlockd is not being used on the host.
|
|
See \fBlvmlockd\fP(8) for more information about shared VGs.
|

.HP
|

\fB-O\fP|\fB--sort\fP \fIString\fP
|
|
.br
|
|
Comma-separated ordered list of columns to sort by. Replaces the default
|
|
selection. Precede any column with \fB-\fP for a reverse sort on that column.
|
|
.
|
|
.HP
|
|
\fB-t\fP|\fB--test\fP
|
|
.br
|
|
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.
|
|
.
|
|
.HP
|

.I 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 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): \fIPV\fP[\fB:\fP\fIPE\fP\fB-\fP\fIPE\fP]...
|
|
Start and length range (counting from 0): \fIPV\fP[\fB:\fP\fIPE\fP\fB+\fP\fIPE\fP]...
|
|
.TP

.I Tag
|

Tag name. See \fBlvm\fP(8) for information about tag names and using tags
|

in place of a VG, LV or PV.

.TP
|

.I String
|
|
See the option description for information about the string content.
|
|
.TP
|
|
.IR 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:
|
|
.BR b | B
|
|
is bytes,
|
|
.BR s | S
|
|
is sectors of 512 bytes,
|
|
.BR k | K
|
|
is KiB,
|
|
.BR m | M
|
|
is MiB,
|
|
.BR g | G
|
|
is GiB,
|
|
.BR t | T
|
|
is TiB,
|
|
.BR p | P
|
|
is PiB,
|
|
.BR e | E
|
|
is EiB.
|
|
(This should not be confused with the output control --units, where
|
|
capital letters mean multiple of 1000.)

.SH ENVIRONMENT VARIABLES
|
|
.
|
|
See \fBlvm\fP(8) for information about environment variables used by lvm.
|
|
For example, LVM_VG_NAME can generally be substituted for a required VG parameter.
