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