	sbd uses a shared storage device as a medium to communicate
	fencing requests. This allows clusters without network power
	switches; the downside is that access to the shared storage
	device becomes a Single Point of Failure.

	It requires sbd to be configured. Please read
	http://linux-ha.org/wiki/SBD_Fencing!
