vgscan

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(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 accordingly.
