I am currently in the process of setting up a Riak cluster and I encountered a problem where my cluster would not start if I change the -name parameter in the vm.args file.
After some searching, I found this official link with this notice:
Following the first option to delete the contents of the ring directory (I built from the source, so my ring directory was at /riak-1.4.7/rel/riak/data/ring/), I then managed to successfully restart the cluster with ./riak start.
