Because the alternative is to lose the ability to fence the node if you lose one of the fencing devices. (I assume you'd be unable to confirm the fence if one of them was without power?) You need to look at the larger picture: even though each node is only on one power supply, the whole cluster is on two. Alternatively, use a mechanism like SBD which doesn't fence via the power device, but uses the shared storage. Regards, Lars -- Architect Storage/HA, OPS Engineering, Novell, Inc.
