Eg, if you specify the master as master.domain.local? This may be a silly question but will it cause any issues? The idea being that if the master goes down, we can relaunch it and just change the DNS to point to the new server.
Some follow on questions:
If we do this and change the DNS, will the nodes resolve the change automatically?
If there are 2 master servers running, but only 1 of them is being sent data, will it cause any issues? Eg, if we do relaunch the server and then the original one recovers.
