DESCRIPTION

       When called without the --cache option, pvscan lists PVs on the system, like pvs(8) or pvdisplay(8).

       When  --cache  is  used,  pvscan  updates  runtime  lvm  state  on  the  system,  or  with  -aay performs
       autoactivation.

       pvscan --cache device

       If device is present, lvm records that the PV on device is online.  If device is not present, lvm removes
       the online record for the PV.  pvscan only reads the named device.

       pvscan --cache

       Updates the runtime state for all lvm devices.

       pvscan --cache -aay device

       Performs  the  --cache  steps for the device, then checks if the VG using the device is complete.  If so,
       LVs in the VG are autoactivated, the same as vgchange -aay vgname  would  do.   (A  device  name  may  be
       replaced with major and minor numbers.)

       pvscan --cache -aay

       Performs the --cache steps for all devices, then autoactivates any complete VGs.

       pvscan --cache --listvg|--listlvs device

       Performs  the --cache steps for the device, then prints the name of the VG using the device, or the names
       of LVs using the device.  --checkcomplete is usually included to check if all PVs for the VG or  LVs  are
       online.   When this command is called by a udev rule, the output must conform to udev rule specifications
       (see --udevoutput.)  The udev rule will use the results to perform autoactivation.

       Autoactivation of VGs or LVs can be enabled/disabled using vgchange or lvchange with  --setautoactivation
       y|n, or by adding names to lvm.conf(5) activation/auto_activation_volume_list

       See lvmautoactivation(7) for more information about how pvscan is used for autoactivation.

OPTIONS

       -a|--activate y|n|ay
              Auto-activate LVs in a VG when the PVs scanned have completed the VG.  (Only ay is applicable.)

       --autoactivation String
              Specify  if autoactivation is being used from an event.  This allows the command to apply settings
              that are specific to event activation, such as  device  scanning  optimizations  using  pvs_online
              files created by event-based pvscans.

       --cache
              Scan one or more devices and record that they are online.

       --checkcomplete
              Check  if all the devices used by a VG or LV are present, and print "complete" or "incomplete" for
              each listed VG or LV.  This option is used as a part of event-based autoactivation, so pvscan will
              do nothing if this option is set and event_activation=0 in the config settings.

       --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.

       -e|--exported
              Only show PVs belonging to exported VGs.

       -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.

       --listlvs
              Print a list of LVs that use the device.

       --listvg
              Print the VG that uses the device.

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

       --longhelp
              Display long help text.

       -j|--major Number
              The major number of a device.

       --minor Number
              The minor number of a device.

       --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.

       --noudevsync
              Disables  udev  synchronisation.  The  process  will  not wait for notification from udev. It will
              continue irrespective of any possible udev processing in the background. Only use this if udev  is
              not running or has rules that ignore the devices LVM creates.

       -n|--novolumegroup
              Only show PVs not belonging to any VG.

       --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'.

       --reportformat basic|json
              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. See lvmreport(7) for more information.

       -s|--short
              Short listing format.

       -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.

       --udevoutput
              Command output is modified to be imported from a udev rule.

       -u|--uuid
              Show UUIDs in addition to device names.

       -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.

       --vgonline
              The  first  command  to  see  a  complete  VG  will report it uniquely.  Other commands to see the
              complete VG will report it differently.

       -y|--yes
              Do not prompt for confirmation interactively but always assume the answer yes.  Use  with  extreme
              caution.  (For automatic no, see -qq.)

VARIABLES

       PV     Physical  Volume  name,  a  device  path under /dev.  For commands managing physical extents, a PV
              positional arg generally accepts a suffix indicating a range  (or  multiple  ranges)  of  physical
              extents  (PEs). When the first PE is omitted, it defaults to the start of the device, and when the
              last PE is omitted it defaults to end.  Start and end range (inclusive): PV[:PE-PE]...  Start  and
              length range (counting from 0): PV[:PE+PE]...

       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.
