Doing what Sean suggested worked (or just specifying the chash_fun in the default_bucket_props). Now I'm running into weird behavior that I'm guessing is related to the n_val setting. I'm running three nodes all on separate machines joined with a ring partition size of 64 (22,21,21). On a fourth machine I'm running a load test in which a process spawns 10 threads per node, each thread connecting to a one of the nodes via protobuffs getting and putting random key/values in one bucket. In my previous tests I used the default settings for the bucket (n_val of 3) and everything ran smoothly for many hours. Now I'm trying to set the default_bucket_props just changing the n_val to 1. No errors in the logs and all clients connect successfully. However, pretty much all communication times-out which does not happen with the default bucket props (changing the n_val back to 3 fixes the problem).
