How many nodes do you want run? Keep in mind that with only 2 nodes, fencing off the right one is by definition an undecidable problem. That's one of the features of the current linux HA stack that makes one want to go BSD/CARP.
And if you want to run fully distributed, you might want to look at redis in the first place.
