DNS Clustering Confusion
I have read so many articles that my eyes bleed. But, yet, no matter what I do, it seems DNSOnly is an issue.
My setup
1. Multiple Cpanel hosting nodes several locations
2. ONE DNSOnly elsewhere for failovers
Here is the config
ns1 (full cpanel node with hosting accounts)
ns2 (DNSOnly)
cpanel3, cpanel4, etc
Let just discuss a simple scenario...
On NS1, NS2 is set as 'WRITE ONLY'
On NS2, NS1 is set as 'STANDALONE'
So, any changes or syncs from NS1 should change records on NS2. Changes made on NS2 should be ignored (not making changes there anyways).
So, I deleted a ZONE on NS1, but it will not delete from NS2. I synced from both sides, but it will not disappear.
I will avoid discussing issues with cpanel3 and cpanel4 for now...I just need to understand the cluster dynamic, and why these changes do not appear.

On ns1: - Add your ns2 nameserver, and set it to "Synchronize changes" - do not add a reverse trust - there's no need for it. on cpanel3,4,5.... (I assume full cPanel servers?): - Add ns1 and ns2, set both to "Synchronize changes" - do not add a reverse trust - there's no need for it. The I happen to do a similar setup, where my "ns1" is also a full cPanel server, and ns2, ns3, ns4 are all "DNS Only", and the easy way is to just keep it simple, and only add the servers from the cPanel machine that you expect zone changes to happen on. But at least, skip the reverse trust part - there's no reason to trust the other way around :-) 0 -
Hello @Ray Hayes, I recommend using the "Direct Links" example at: webserver1 >sync changes> dnsonly1 webserver2 >sync changes> dnsonly1 webserver3 >sync changes> dnsonly1 We do not recommend that you set up the nameserver to synchronize data to a web server, because this creates extraneous zones on the web server. This means that you do not need to log in to WHM on the nameserver and set the web server's DNS role to Synchronize changes. Thank you. 0
