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.
