man vgscan (Administration système) - scan all disks for volume groups and rebuild caches
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(8) 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.
