In my AG, I have two nodes using synchronous commit, automatic failover, allow all connections in primary role, and readable secondary as yes. The failover cluster is using a fileshare witness as the quorum. I have to reboot the secondary replica tonight.
What is the best practice for handling this type of maintenance? Since I have quorum, can I just reboot the secondary? Do I need to drain roles of the secondary in the cluster manager? Is there an AG maintenance mode?
