Can the ring size be changed easily in Riak 2.X? Imagine I have 5 servers originally with a ring_size = 64... If later on I add 5 more servers (10 in total) and I also want to duplicate the partitions, can I just edit the ring_size to 128?
How would be the process to do it? Will it rebalance properly and have no issues?
