    Hello,

    Can anyone tell me what are the exact steps to create and add a new cpanel DNS-Only server to an existing cpanel DNS Cluster?

    (We have 2 existing DNS-Only servers, and want to add a 3rd but it's been many years since we did this.)

    Here is what I have:

    1. Build new cpanel server using DNS-Only. (Let's call it "NewNameserver".)
    2. Login as root to WHM on NewNameserver and click the Home »Clusters »DNS Cluster link.
    3. Click the "Enable DNS Clustering" button.
    4. Ffor EACH web hosting server:
      1. Login as root to WHM on the web hosting server and click the Home »Clusters »DNS Cluster link.
      2. Click the "Configure" button under the "Add a new server to the cluster" section.
      3. Enter the hostname for NewNameserver, root username, and root access hash.
      4. Check the "Setup Reverse Trust Relationship" box.
      5. For DNS Role, choose the Synchronize Changes option.
      6. Click the Submit button.
    5. Go to step #4 and repeat for every web hosting server.
    Is this correct?

    QUESTIONS:
    1. Should we be using "Write-only" as the DNS Role instead of Synchronize Changes?

    2. How do we get all the zonefiles from the existing two DNS-Only servers to copy over to the NewNameserver so all three DNS-Only servers will be serving the same zonefiles?
    Thanks!

    Hello,

    Those are the correct steps, assuming you want to use "Synchronize Changes" as the DNS role instead of "Write Only". You can read the full steps, including information about each DNS role, at:

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

    DNS zones will automatically sync from the hosting servers to the new DNS-Only server after you've setup clustering. However, if you want to manually synchronize your DNS zones, you can review the steps listed on the following document:

    Synchronize DNS Records - Documentation - cPanel Documentation

    Thank you.

    What should be the role for our DNS-Only nameservers where the zonefiles are served from?

    What should be the role for our web hosting servers that are "sending" zonefile updates to the DNS-Only servers?

    Synchronize Changes or Write-Only.

    Thank you.

    Hello, i have the same case, everything seems to be working but i think that @electric miss something:

    For each hosting server, you need to add the new name server on "WHM > Basic WebHost Manager Setup" at the bottom on Nameservers section.

    Now, my question:

    Doing all steps does not write the new ns record to existing zones, the new ns record will write only to new or future zones, so now we need to add the new ns record to existing zones, is there any way to add the new ns record to all existing zones? i have 10000+ zones, doing manually one by one will take me forever.
