VGDISPLAY(8) System Manager's Manual VGDISPLAY(8)
NAME
vgdisplay - Display volume group information
SYNOPSIS
vgdisplay
[ option_args ]
[ position_args ]
DESCRIPTION
vgdisplay shows the attributes of VGs, and the associated PVs and LVs.
vgs(8) is a preferred alternative that shows the same information and
more, using a more compact and configurable output format.

OPTIONS
-A|--activevolumegroups
Only select active VGs. The VG is considered active if at least
one of its LVs is active.
--aligned
Use with --separator to align the output columns
--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 vgs(8) which provides considerably more con-
trol 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 set-
tings. 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 failures.
--ignoreskippedcluster
Use to avoid exiting with an non-zero status code if the command
is run without clustered locking and clustered VGs are skipped.
--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.
--noheadings
Suppress the headings line that is normally the first line of
output. Useful if grepping the output.
--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 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 --ver-
bose. 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. It can also be used to
peek inside the metadata of clustered VGs when clustered locking
is not configured or running. No attempt will be made to commu-
nicate 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. 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 addi-
tional "selected" field (-o selected) showing 1 if the row
matches the selection and 0 otherwise. For non-reporting com-
mands 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
Give a short listing showing the existence of VGs.
-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 col-
umns 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)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
VG
Volume Group name. See lvm(8) for valid names.
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
input unit is specified by letter, followed by |UNIT. UNIT rep-
resents other possible input units: bBsSkKmMgGtTpPeE. b|B is
bytes, s|S is sectors of 512 bytes, k|K is kilobytes, m|M is
megabytes, g|G is gigabytes, t|T is terabytes, p|P is petabytes,
e|E is exabytes. (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.
