LVMDISKSCAN(8)              System Manager's Manual             LVMDISKSCAN(8)

NAME
       lvmdiskscan - List devices that may be used as physical volumes

SYNOPSIS
       lvmdiskscan
           [ option_args ]

DESCRIPTION
       lvmdiskscan  scans all SCSI, (E)IDE disks, multiple devices and a bunch
       of other block devices in the system looking for LVM PVs. The size  re-
       ported  is  the real device size. Define a filter in lvm.conf(5) to re-
       strict the scan to avoid a CD ROM, for example.

       This command is deprecated, use pvs instead.

USAGE
       lvmdiskscan
           [ -l|--lvmpartition ]
           [    --readonly ]
           [ COMMON_OPTIONS ]

       Common options for lvm:
           [ -d|--debug ]
           [ -h|--help ]
           [ -q|--quiet ]
           [ -t|--test ]
           [ -v|--verbose ]
           [ -y|--yes ]
           [    --commandprofile String ]
           [    --config 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 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.

       -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.

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

       --longhelp
              Display long help text.

       -l|--lvmpartition
              Only report PVs.

       --nolocking
              Disable locking.

       --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. 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.

       -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 un-
              usual 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 de-
              tail 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 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.
