I have a 5 node Riak cluster running. I ssh to node 1 and run 'riak-admin test' the output of which is "Node is not running!"..however the REST API responds (eg http://{localhst}:8098/stats returns JSON stats as expected) and I can run a client that hits the ProtoBuf endpoint ok too. I must be making a noob mistake but what? (yes, have tried sudo riak-admin test)
I'm running Riak in a docker container on Debian Jessie host and have established ssh session via docker exec -i -t [container name} bash. I have hit the HTTP endpoint with curl from the session.
