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.
