For the bitcask backend, ring_num_partitions=64 and ring_creation_size=256. I haven't seen where to set ring_num_partitions in app.config. I have about 8 million keys stored in this cluster.
So, how do I bring up a LevelDB node and join to the existing cluster given this 64/256 partitions/creation_size config? Thanks for the help!

Assuming the LevelDB node is empty, you can do the following: 1. Stop the node 2. Clear out the data directories (data/ring, data/leveldb, data/bitcask, data/mr_queue, data/kv_vnode) 3. Verify "ring_creation_size" is set to 256 in the app.config file 4. Start the node 5. Verify "ring_num_partitions" in "riak-admin status" is 256 6. Join the node to the cluster Thanks, Dan Daniel Reverri Developer Advocate Basho Technologies, Inc. d...@basho.com On Fri, Oct 21, 2011 at 9:30 AM, <jim.ad...@comcast.net> wrote: > 64 on the LevelDB vs 256 on the Bitcask.
