Hi, thanks for the articles, it was really interesting reading. I figured out the part with elastic and mongo as we already do have experience with those in our infrastructure. What I wanted to figure out was the high availability of graylog2 servers which is not solved in those articles.
In graylog2 servers, you need to manually specify which node is master. This master then does periodic tasks and the others don't. I would like to solve the problem when you have three nodes (two slaves and one master) and the master dies. When this happens, I would love if one of the slaves took the master role and continued the work. When the original master would be fixed, it would join the cluster as slave, as there already is one master. This is how Elastic is doing it. I experimented with some configuration and the graylog2 cluster can work like that if you say, that all of the nodes are master. Then, the first node in cluster stays master and the others are forced to be slaves. If master dies, one of the slaves becomes master. When I do this configuration, I get alert in graylog-web, that I had more then one master in the cluster and that the other ones were forced to work as slaves, but that 'I should still fix this' which is why I would like to know if there is a proper way of configuring master/master cluster. Thanks!
