VGSCAN(8)VGSCAN(8)NAMEvgscan - scan all disks for volume groups and rebuild caches
SYNOPSISvgscan [-d|--debug] [-h|-?|--help] [--ignorelockingfailure] [--mknodes]
[-P|--partial] [-v|--verbose]
DESCRIPTIONvgscan 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 volumes 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 accordâ
ingly.
