Thanks Greg for the clarification. I wonder if some sort of voting during recovery would be feasible to implement. Having this available would make a 3x replica scheme immensely more useful. In my current understanding Ceph has no guards against local bit rot (e.g., when a local disk returns incorrect data). Or is there already a voting scheme in place during deep scrub?
