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 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.

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
              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.

       --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.

       -l|--lvmpartition
              Only report PVs.

       --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
              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 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.
