vgscan(8) scan all disks for volume groups and rebuild caches


vgscan [--commandprofile ProfileName] [-d|--debug] [-h|-?|--help] [--ignorelockingfailure] [--mknodes] [--notifydbus] [-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(8) for common options.
Also checks the LVM special files in /dev that are needed for active logical volumes and creates any missing ones and removes unused ones.
Send a notification to D-Bus. The command will exit with an error if LVM is not built with support for D-Bus notification, or if the notify_dbus config setting is disabled.
Scan devices for LVM physical volumes and volume groups and instruct the lvmetad daemon to update its cached state accordingly.
