They're effectively equal

Hi all,
Found the problem/solution.
With the first cluster, I set it up with a ring size of 64. Prior to
loading data. I stopped the node(s), changed the ring size to 256, then
restarted.
Therefore, if I want to add a new node, I FIRST must start the node with a
ring size of 64, then stop it, change the conf for a ring size of 256, then
start, then stage, plan, and commit.
I am still not sure the relation ship with ring size and ring partitions.
Sincerely,
Robert

Hi All,
I've got a cluster in 2.1.1 and was wanting to join a 2.1.3 node to it
I am getting the following error:
# ./bin/riak-admin cluster join a-backend@10.0.0.199
Failed: a-backend@10.0.0.199 has a different ring_creation_size
So... for the new 2.1.3
# ./bin/riak-admin status | grep ring

ring_members : ['node-template@10.0.0.54']

AND for node a-backend@10.0.0.199

The 'ring_num_partitions' are different which leaves me to believe this is
the cause.
A.) How do I increase the 'ring_num_partitions' to 256 in the 2.1.1
cluster� **OR**
B.) How do I decrease the 'ring_num_partitions' to 64 in the 2.1.3 node?
Any ideas? recommendations?
Thanks in advance,
Robert
