I'm testing out the HA features using server version 3.0.2 and it seems to
fulfill my requirements.
There's one thing I don't really understand, and I was hoping someone would
be able to enlighten me.
I have a two (2) node HA cluster, for convenience, let's call them *
NODE-MASTER* and *NODE-SLAVE*.
1. I publish 100k messages to NODE-MASTER, and they are replicated to *
2. I take down *NODE-MASTER* using *rabbitmqctl*.
3. NODE-SLAVE is promoted to master and retains the messages it
4. Bring *NODE-MASTER* back up and into the cluster
This all works as I expect it to, but after the former master node rejoins
I see a message in the web-management console saying that one of the nodes
is unsynchronised (see screenshot).
Why does this occur, and more importantly, what does it mean in this
