[_VGDISPLAY_(8)](https://www.chedong.com/phpMan.php/man/VGDISPLAY/8/markdown)                           System Manager's Manual                          [_VGDISPLAY_(8)](https://www.chedong.com/phpMan.php/man/VGDISPLAY/8/markdown)

## 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)](https://www.chedong.com/phpMan.php/man/vgs/8/markdown) is a preferred alternative that shows the same information and more, using a more com‐
       pact and configurable output format.

## OPTIONS


### -A --activevolumegroups
              Only  select active VGs. The VG is considered active if at least one of its LVs is ac‐
              tive.

### --aligned
              Use with --separator to align the output columns

### --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)](https://www.chedong.com/phpMan.php/man/vgs/8/markdown) which provides considerably more control over the output.

### -C --columns
              Display  output  in columns, the equivalent of [**vgs**(8)](https://www.chedong.com/phpMan.php/man/vgs/8/markdown).  Options listed are the same as
              options given in [**vgs**(8)](https://www.chedong.com/phpMan.php/man/vgs/8/markdown).

       **--commandprofile _**String_
              The command profile to use for command configuration.  See [**lvm.conf**(5)](https://www.chedong.com/phpMan.php/man/lvm.conf/5/markdown) for more infor‐
              mation about profiles.

       **--config _**String_
              Config settings for the command. These override [**lvm.conf**(5)](https://www.chedong.com/phpMan.php/man/lvm.conf/5/markdown) settings.  The String  arg
              uses the same format as [**lvm.conf**(5)](https://www.chedong.com/phpMan.php/man/lvm.conf/5/markdown), or may use section/field syntax.  See [**lvm.conf**(5)](https://www.chedong.com/phpMan.php/man/lvm.conf/5/markdown)
              for more information about config.

       **--configreport log**|**vg**|**lv**|**pv**|**pvseg**|**seg**
              See [**lvmreport**(7)](https://www.chedong.com/phpMan.php/man/lvmreport/7/markdown).

### -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  command.   Devices  not
              listed will appear to be missing. This option can be repeated, or accepts a comma sep‐
              arated 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)](https://www.chedong.com/phpMan.php/man/lvmdevices/8/markdown) command.  This  overrides  the  [**lvm.conf**(5)](https://www.chedong.com/phpMan.php/man/lvm.conf/5/markdown)  **de‐**
              **vices/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 de‐
              bugging.

### --foreign
              Report/display foreign VGs that would otherwise be skipped.   See  [**lvmsystemid**(7)](https://www.chedong.com/phpMan.php/man/lvmsystemid/7/markdown)  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.

       **--journal _**String_
              Record information in the systemd journal.  This information is in addition to  infor‐
              mation 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)](https://www.chedong.com/phpMan.php/man/lvmlockd/8/markdown) for more informa‐
              tion.

### --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 grep‐
              ping 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 produce incorrect results.


### --nosuffix
              Suppress the suffix on output sizes. Use with --units (except h and H)  if  processing
              the output.

### -o --options _
              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  de‐
              fault  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 com‐
              pact 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)](https://www.chedong.com/phpMan.php/man/lvm.conf/5/markdown) re‐
              port section for more config options.  See [**lvmreport**(7)](https://www.chedong.com/phpMan.php/man/lvmreport/7/markdown) for more information about re‐
              porting.

       **--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 al‐
              so 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  commu‐
              nicate  with  the  device-mapper  kernel  driver,  so  this option is unable to report
              whether or not LVs are actually in use.

### -S --select _
              Select objects for processing and reporting based on specified criteria.  The criteria
              syntax is described by **--select help **and [**lvmreport**(7)](https://www.chedong.com/phpMan.php/man/lvmreport/7/markdown).  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-report‐
              ing 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)](https://www.chedong.com/phpMan.php/man/lvmlockd/8/markdown) for more information about shared VGs.

### -s --short
              Give a short listing showing the existence of VGs.

### -O --sort _
              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 read‐
              ing 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)er‐
              abytes, (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)](https://www.chedong.com/phpMan.php/man/lvm/8/markdown) for valid names.

       _Tag_    Tag name.  See [**lvm**(8)](https://www.chedong.com/phpMan.php/man/lvm/8/markdown) 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)](https://www.chedong.com/phpMan.php/man/lvm/8/markdown) for information about environment variables used by lvm.  For example, LVM_VG_NAME
       can generally be substituted for a required VG parameter.
