NAME
       pvscan - scan all disks for physical volumes

SYNOPSIS
       pvscan  [-d|--debug]  [-h|--help]  [-v|--verbose]  [--version]  [--ignorelockingfailure]  [-e|--exported] [-n|--novolumegroup] [-s|--short]
       [-u|--uuid]

       pvscan [-d|--debug] [-h|--help] --cache [-a|--activate ay] [-b|--background] [--major major --minor minor | DevicePath | major:minor]...

DESCRIPTION
       pvscan scans all supported LVM block devices in the system for physical volumes.

OPTIONS
       See lvm(8) for common options.

       -e, --exported
	      Only show physical volumes belonging to exported volume groups.

       -n, --novolumegroup
	      Only show physical volumes not belonging to any volume group.

       -s, --short
	      Short listing format.

       -u, --uuid
	      Show UUIDs (Uniform Unique Identifiers) in addition to device special names.

       -a, --activate ay
	      Together with the information already cached in lvmetad, automatically activate any logical volumes that	become	activatable  after
	      the  scan  done  on  one or more devices.  The logical volume to autoactivate is matched against the activation/auto_activation_vol-
	      ume_list set in lvm.conf. If this list is not set, then all volumes are considered for autoactivation. The autoactivation is not yet
	      supported for logical volumes that are part of partial or clustered volume groups.

       -b, --background
	      Run the command in the background.

       --cache [--major major --minor minor | DevicePath | major:minor ]...
	      Scan  one  or more devices and instruct the lvmetad daemon to update its cached state accordingly.  Called internally by udev rules.
	      All devices listed explicitly are processed regardless of any device filters set using devices/filter configuration setting. To fil-
	      ter  devices  even  in this case, the devices/global_filter must be used.  If lvmetad has not yet cached any metadata or the filters
	      have recently been changed, then all devices may be scanned, effectively ignoring the rest of the command line.  Otherwise,  if  all
	      the devices referenced on the command line contain metadata in the default lvm2 format, other devices are not accessed.  If metadata
	      written using the obsolete GFS pool format is encountered, this is ignored and so lvmetad should not be used.
