A replica set in MongoDB must have at least 3 nodes. The graylog-ctl script doesn't support creating MongoDB-only nodes, so I'd recommend simply running 3 Graylog+MongoDB nodes. This being said, the graylog-ctl script doesn't support creating MongoDB replica sets, so you'd have to set it up manually anyway and couldn't use the graylog-ctl script. Second, what instance type I should use for each? I was told in IRC a good > size for the elasticsearch nodes is *m4.xlarge*. What about the server > nodes?
