DNS configuration not replicated by HA


Doing some configuration tweaks on my HA setup (10.13.66-7) I noticed that the DNS configuration is not replicating to the other node, I had to manually switch nodes and change the configuration. I also confirmed that the /etc/resolv.conf file does not get modified (or synchronized) on the slave node.

The Cluster Health Check runs fine and everything seems to be ok. Is this expected behavior? if yes then, what other configuration settings or screens do not synchronize and need to be manually done on both nodes?
