Why I see fault tolerance = 2 machine in the status output below when number of co-ordinators are 5 and all nodes are available for redundancy = three_datacenter. I was expecting fault tolerance of 3 for machines more than 5 by default.
On some of the deployment for same configuration I do see fault tolerance = 3 machines so not sure in this case why it is showing 2 only.
