In case someone stumbles here looking for an answer. (Not sure why it
wasn't posted here)
Thanks to Matthias the answer is as follows:
The old master rejoins the cluster as a slave with an empty and
unsynchronized queue and catches up to the current master. This is of
course unless all nodes go down, then the last disc node to go down should
be brought back up in order to get the messages that were persisted to disc.
