Hi there,

I know the recommendation is to have a cluster out of 2 or odd number of nodes, but I have this constraint of having only even number of nodes. Any particular suggestion on how I can build my HA cluster such that all failover/fencing related cases are taken care of.

Q2: My cluster needs to be running in Active/Passive mode, just that the Passive nodes also should be running some common service say serv.sh but this should be running with different port on Passive nodes and different on the Active node.

Can somebody please help me build a full proof & efficient cluster for the same?
