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

NAME         top

       lvmdiskscan - List devices that may be used as physical volumes

SYNOPSIS         top

       lvmdiskscan
           [ option_args ]

DESCRIPTION         top

       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 reported is the real device size. Define a filter in lvm.conf(5)
       to restrict the scan to avoid a CD ROM, for example.
       This command is deprecated, use pvs instead.

           [    --profile String ]
           [    --version ]

OPTIONS         top

       --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.
       --longhelp
              Display long help text.
       -l|--lvmpartition
              Only report PVs.
       --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.
       -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         top

       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         top

       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.
