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

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 volumes and creates any missing ones and removes unused
              ones.
