DESCRIPTION
       vgscan scans all supported LVM block devices in the system for VGs.

USAGE
       vgscan
           [    --ignorelockingfailure ]
           [    --mknodes ]
           [    --notifydbus ]
           [    --reportformat basic|json ]
           [ COMMON_OPTIONS ]

       Common options for lvm:
           [ -d|--debug ]
           [ -h|--help ]
           [ -q|--quiet ]
           [ -t|--test ]
           [ -v|--verbose ]
           [ -y|--yes ]
           [    --commandprofile String ]
           [    --config String ]
           [    --devices PV ]
           [    --devicesfile String ]
           [    --driverloaded y|n ]
           [    --lockopt String ]
           [    --longhelp ]
           [    --nolocking ]
           [    --profile String ]
           [    --version ]

OPTIONS
       --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.

       -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.

       -h|--help
              Display help text.

       --ignorelockingfailure
              Allows a command to continue with read-only metadata operations
              after locking failures.

       --lockopt String
              Used to pass options for special cases to lvmlockd.  See
              lvmlockd(8) for more information.

       --longhelp
              Display long help text.

       --mknodes
              Also checks the LVM special files in /dev that are needed for
              active LVs and creates any missing ones and removes unused ones.

       --nolocking
              Disable locking.

       --notifydbus
              Send a notification to D-Bus. The command will exit with an error
              if LVM is not built with support for D-Bus notification, or if the
              notify_dbus config setting is disabled.

       --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'.

       --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.

       -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.

       -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
       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.
