vgscan - scan all disks for volume groups and rebuild caches vgscan [-d|--debug] [-h|-?|--help] [--ignorelockingfailure] [--mknodes] [-P|--partial] [-v|--verbose] 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.

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.
