I think the main advantage of nodetool is that you don't have to calculate / determine which nodes to run repair on; you can just run nodetool repair -pr on every node without doing redundant work. If you run nodetool repair without -pr, then you need to run repair against only every RFth node (every third node, in your case, which for 6 nodes total is 2 nodes, as you said) to avoid doing redundant work. The end result is the same as far as I know. -- mithrandi, i Ainil en-Balandor, a faer Ambar
