NAME
       vgscan -- scan all disks for volume groups and rebuild caches

SYNOPSIS
       vgscan	[--commandprofile   ProfileName]  [-d|--debug]	[-h|-?|--help]
       [--ignorelockingfailure] [--mknodes] [-P|--partial] [-v|--verbose]

DESCRIPTION
       vgscan scans all SCSI, (E)IDE disks, multiple devices and  a  bunch  of
       other  disk  devices in the system looking for LVM physical volumes and
       volume groups.  Define a filter in lvm.conf(5) to restrict the scan  to
       avoid a CD ROM, for example.

       In  LVM2, vgscans take place automatically; but you might still need to
       run one explicitly after changing hardware.

OPTIONS
       See lvm(8) for common options.

       --mknodes
	      Also checks the LVM special files in /dev that  are  needed  for
	      active  logical volumes and creates any missing ones and removes
	      unused ones.

       --cache
	      Scan devices for LVM physical  volumes  and  volume  groups  and
	      instruct	the  lvmetad daemon to update its cached state accord-
	      ingly.
