Chapter 3. GNBD Driver andCommand UsageThe Global Network Block Device (GNBD) driver allows a node to export its local storage as aGNBD over a network

NoteA server should not import the GNBDs to use them as a client would. If a serverexports the devices uncached, the underlying devices may also be us

The UID is used by device-mapper multipath to determine which devices belong in a mul-tipath map. A device must have a UID to be multipathed. However,

The gnbd.ko kernel module must be loaded on a node before it can import GNBDs. When GN-BDs are imported, device nodes are created for them in /dev/gnb
