<p class=MsoNormal>Hi,<br>
<br>
Suppose that I have a cluster with an odd-number of nodes - say 3 nodes.
In the event of a network partition, split brain is avoided by moving (or
keeping) leadership to the partition that contains two nodes. <br>
<br>
In the event of routine maintenance, where one of the members needs to be
brought down in order to be replaced or upgraded, I now have a 2-node system
which presumably is at risk of split brain in the event of a network partition
happening during the maintenance window.<br>
<br>
What is the best way of reducing the risk of split brain during the maintenance
window when the cluster is not at full strength ?<br>
<br>
regards,<br>
