    Hello,

    I have read a lot on this topic, but still think it is somewhat confusing so want to ask to be sure.

    I have a couple of web servers running cPanel. I am also running 2x cPanel DNS Only in VPS.

    I want to enable DNS clustering.

    So far I have figured out the following configuration:

    WEB SERVER 1:
    -> DNS ONLY1 "synchronize"
    -> DNS ONLY2 "synchronize"

    WEB SERVER 2:
    -> DNS ONLY1 "synchronize"
    -> DNS ONLY2 "synchronize"

    cPanel DNS ONLY 1:
    -> WEB SERVER 1 "standalone"
    -> WEB SERVER 2 "standalone"

    cPanel DNS ONLY 2:
    -> WEB SERVER 1 "standalone"
    -> WEB SERVER 2 "standalone"

    I think I got this part correct?

    What I want to know is: do I have to add cPanel DNS ONLY 1 to the cluster config on the other DNS server and vice versa? Or will zones automatically synchronize between the DNS servers in the cluster?

    And: should I add each WEB SERVER to every other web server cluster config?

    I am pretty sure I should only add the DNS servers on the cluster config for the web servers, and only web servers on the cluster config for the DNS servers, but I want to be sure.

    Thank you,
    Sindre

    Hello :)

    The current configuration you have in place is valid.

    No, you do not need to synchronize DNS-Only servers to each other, or configure them in the cluster together at all.
