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 denotes 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 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 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.

-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.

-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.

–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 (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
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.

–reportformat basic*|*json
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. See *lvmreport*(7) for more information.

-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.

-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 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.

-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 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): 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 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.
