I have a new cPanel server (Server A) and I would like to have an existing cPanel server (Server B) be a DNS Cluster partner with it. However, sometime next year another new cPanel server will come online (Server C), then I will want to remove Server B from the cluster and add Server C:

NOW: Server A <--> Server B
FUTURE: Server A <--> Server C

The question is: When I remove Server B from the Cluster, what do I need to do, to get the old Server A zone files off of Server B... and the Server B zone files off of Server A? Is that what the DNS Cleanup feature in WHM does? It says it removes "duplicated entries" but that isn't really what I need.

If this doesn't make sense, let me know! Otherwise, thanks in advance for a push in the right direction!

Hi Michael. Hmmm... OK... do you have any tips on the process to "manually delete the DNS Zones on a server after removing it from the cluster" ?

You can login to your WHM and remove the zones from the delete DNS zone section.

Main >> DNS Functions >> Delete DNS zone

Multiple zone selection is enable in whm and you can remove them all form there.

You can also remove them by hand via console by deleting the zone file in /var/named/<domain>.db but you need to remove the entries in /etc/named.conf for each zone also.

WHM way should be the easiest.

Hello :)

You could look at the files on the server that list your domain names. EX:

/etc/localdomains
/etc/remotedomains

Use these files to populate a list of domain names. Then, develop a custom bash script to exclude those domain names from deletion or copy the zones to another location. This will allow you to delete the DNS zones all domain names not added to the server.

Thank you.
