Hello, I have a 10 node cluster with 12 disks/devices per node. I have setup riak in a jbod environment with separate riak nodes per device, resulting in 120 riak nodes total. Based on the documentation, I set the ring_creation_size to 4096, which gives me ~34 partitions/node and allows me to expand the cluster in the future. With this value, soon after starting the 12 riak nodes on a given physical node, I get "Too many processes" errors and the riak nodes fail. Decreasing the value of ring_creation_size to 1024 (giving me ~8 partitions per riak node) prevents the riak nodes from failing, but then expanding the cluster becomes a problem (30 physical nodes would result in only ~3 partitions per node).
Is there a reasonable limit on the value of ring_creation_size?
