VGSCAN(8)                            System Manager's Manual                            VGSCAN(8)

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 vol‐
              umes 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 accordingly.
