vgscan(8) -- Linux man page

 

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.
