Hi David, Matt, We've just discussed this and its a bit tricky. For 4 servers with N=3 it is possible to stop 2 nodes, (say 3 and 4) and then send a "force-remove" command to the remaining servers (1 and 2).
Then you could start (3 and 4), and send *them* a force-remove of (1 and 2). This is risky because you're only guaranteed one replica of the data on each of the new clusters. The other risk is that new data written to (1 and 2) will not be replicated over to (3 and 4). Are you planning on re-joining the cluster back up afterwards? There's better ways than doing "mitotis" (although i love the name). Look into Multi Data Center Replication, or just add new nodes and do a force-replace. If the data is small enough, you could use the backup commn Hope i got this right, i'm quite new to this myself.
