Running multiple Riak instances.

Misha,

I *think* I had the same problem.

Perhaps you started your nodes when they were still called 'riak', and
that may be the reason why -progname remains?

Did you update the ring file? This worked for me:

riak-testing/bin/riak-admin reip riak at 127.0.0.1 testing at 127.0.0.1
riak-production/bin/riak-admin reip riak at 127.0.0.1 production at 127.0.0.1
