Adding a third DNS server, couple questions

[domeneas]

Hello,

so I have an odd issue in a test environment.

I have 2 DNSOnly servers serving 4 Cpanel servers, and wanted to add a third DNSOnly server.

I am clicking around, looking at the settings of my original 2, and see something I was not aware of.

On the 2 original DNSOnly servers, 2 of my 4 Cpanel servers are added as "Standalone" servers under "DNS Cluster" - "Servers in your DNS cluster". 2 cpanel servers are not.

The DNSOnly servers do not have each other in the "Servers in your DNS cluster". Their "Path Diagram" shows only their own hostname.

This just seems like its set up very wrongly by someone.

On all the 4 Cpanel servers, both DNSOnly servers are added identically, with "Synch Changes" and "reverse trust setups". Their "Path diagram" shows:
Cpanel1.net

• ↳ ns2.dnsonly.com
• ↳ ns1.dnsonly.com

I do notice that when doing some tests, with "Synchronize DNS Changes" - "Synch all zones to all servers" on the cpanel servers that it will synch a different amount of zones depending on what Cpanel server I do it from.

What has been done wrong here? All 4 cpanel servers are able to server live domains when tested.

Thanks in advance.

Hello

I don't see any issues with how the cluster is configured. Direct links are the preferred method of linking cPanel servers to cPanel DNS-Only servers, as documented at:

Guide to DNS Cluster Configurations - cPanel Knowledge Base - cPanel Documentation

The reverse trust relationship is not required if you are only syncing changes from the cPanel server to the DNS-Only server.

Thank you.
