Question regarding dns clusters

Is it possible and or recommended to have a DNS cluster, between 2 full fledged whm servers? Except one of them is a new build and doesn't have any accounts yet.

  There shouldn't be an issue with having a DNS cluster setup between two full-fledged WHM, one of which having no accounts. I personally would recommend taking a look at using the DNSONLY cPanel installs for the actual nameservers, however.

  I do plan on getting a dns only server, but right now not at that point yet, also I want to add that both servers will have accounts at 1 point sorry if I wasn't clear on that.

  Having accounts on both servers should not be problematic!

  I was reading different things about that, which is why I was a little unclear. Thanks for replying though and hope you had a good Christmas.

  There is always potential for issues to arise. That said, the configuration you describe isn't inherently increasing the likelihood of experiencing said issues, in my opinion (based solely on my understanding of the DNS cluster you are proposing-one with WHM/cPanel Standard Nodes, each contributing 1 nameserver to the cluster). Another way to go, that would improve scalability/performance, would be to create 2 tiny VPS (~10 gb SSD+~1-2gb ram+1 vCPU), install DNSonly on each and disable nameservers on the WHM servers (or, alternatively, using the WHM servers to provide a BIND backend for redundancy/caching purposes). The web servers will synchronize changes to the DNSonly nameservers, while the DNSOnly will have standalone connections to the WHM servers. I know that probably sounds unnecessarily complex at the moment. You will thank yourself later, as it actually simplifies scaling the cluster moving forward.

  Thanks for replying though and hope you had a good Christmas.

  
  Thanks, it was fine.
