NAME
       pvscan — scan all disks for physical volumes

SYNOPSIS
       pvscan  [--commandprofile ProfileName] [-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_activa‐
              tion_volume_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  filter  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 com‐
              mand 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.
