I’m currently in the middle of trying to set up a cluster of EventStore database nodes across multiple datacentres for high availability. I’ve got most of it working quite happily, but we have a preferred datacentre for our all of our cluster master roles for data tier services (we use SQL and MongoDB here as well) and I can’t seem to find a way to manually force a particular database node to be the EventStore cluster master (leader?) so that the role lives in our primary datacentre.
Is it possible to force a particular database node to be the master, and if so, how do I go about doing it - e.g. is there an api call or a command line option?
