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
       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
       --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) set-
              tings.  The String arg uses the same format as  lvm.conf(5),  or
              may use section/field syntax.  See lvm.conf(5) for more informa-
              tion 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) com-
              mand.  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.   out-
              put: record the default command output.  debug: record full com-
              mand debugging.
       --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.
       --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.
       --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
              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 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: 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.
