Is this how people have it I think it's basically about your sleep at night or at weekends: If the cluster can manage a problem without requiring your intervention, that's good (for your sleep). In practice there had been many situations when both nodes in a 2-node cluster did fence. So without auto-starting the cluster nodes after boot, you clearly have a "no sleep" situation; specifically if your cluster provides services for more external machines. > configured?

I think there is no "one size fits all" solution: Both variants have advantages and disadvantages.
