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

SYNOPSIS
       vgscan  [-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 for common options.

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