Named fails to start with "zone '': already exists previous definition (Cpanel DNS Only)

This trick allows you to remove duplicated DNS entries on a DNS Only cluster with Cpanel.

As you can see below, on one of the Cpanel DNS Only servers, named is having trouble starting as there are duplicate entries within the named.conf.

The easiest fix for this is to run the following commands on each of the DNS only servers in the cluster.

mv -v /etc/named.conf{,.bak}

You can also double-check within WHM of the Cpanel DNS only server.
