NAME

       lvscan - List all logical volumes in all volume groups

SYNOPSIS

       lvscan option_args
           [ option_args ]
           [ position_args ]

DESCRIPTION

       lvscan  scans all VGs or all supported LVM block devices in the system for LVs. The output
       consists of one line for each LV indicating whether or not it is  active,  a  snapshot  or
       origin,  the  size  of the device and its allocation policy. Use lvs(8) or lvdisplay(8) to
       obtain more comprehensive information about LVs.

           [    --profile String ]
           [    --version ]

OPTIONS

       -a|--all
              Show information about internal LVs.  These are components of normal LVs, such as
              mirrors, which are not independently accessible, e.g. not mountable.

       -b|--blockdevice
              No longer used.

       --cache
              Scan the devices used by an LV and send the metadata to lvmetad.

       --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 settings.  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.

       -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.

       -h|--help
              Display help text.

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

       --longhelp
              Display long help text.

       --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.  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 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.  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

       LV
              Logical  Volume  name.  See lvm(8) for valid names.  An LV positional arg generally
              includes the VG name and LV name, e.g. VG/LV.

       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: 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.
