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

SYNOPSIS
       vgscan	[--commandprofile   ProfileName]  [-d|--debug]	[-h|-?|--help]
       [--ignorelockingfailure]	 [--mknodes]   [--notifydbus]	[-P|--partial]
       [--reportformat {basic|json}] [-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.

       --notifydbus
	      Send  a  notification  to	 D-Bus.	 The command will exit with an
	      error if LVM is not built with support for  D-Bus	 notification,
	      or if the notify_dbus config setting is disabled.

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