NAME

       lvscan — List all logical volumes in all volume groups

SYNOPSIS

       lvscan
           [ option_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.

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.

       --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
              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 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.

       --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.

       --longhelp
              Display long help text.

       --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.

       --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
              Prevent  the  command  from  making  changes,  including  activation  and  metadata updates.  (See
              --permission r for read only LVs.)

       --reportformat basic|json|json_std
              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. json_std produces report output in JSON format which is
              more compliant with JSON standard.  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.
