Hi Walter, It is not recommended to run more than 1 node per machine. Also, creating a new node by copying/pasting an existing node is not a good idea.
Were you seeing "insufficient vnodes" before you tried adding nodes? Was the node under any load? MapReduce, ListKeys, etc. What does "riak-admin status" return on the original node? What does "riak-admin ring_status" return on the original node? What does "riak-admin "member_status" return on the original node? I am concerned that the addition of copied nodes may be creating additional issues. I would recommend getting the cluster back to a steady state with a single node. Once this is complete we can review the issues and determine what the problem might be. Thanks, Dan Daniel Reverri Developer Advocate Basho Technologies, Inc.
