Dns entry already exists

I got this error while trying to add a domain as an add-on to the primary cPanel account. The domain is already pointing into another server, which also using the same DNS cluster and that was actually creating the problem.
I have tried a lot and got this solution!!

Error details:

A DNS entry for “xxx.com” already exists. You must remove this DNS entry from all servers in the DNS cluster to proceed.

Please do follow the steps below:

Step 1 : SSH to the server as root user where you are trying to add the domain.

Step 2 : Check the zone list. You can check it under the directory “/var/named.” There might be an entry for this domain. If so, remove it and try to add the domain again.

If it is not in the server, sure, it will be in any other servers using the same DNS cluster. Please confirm the domain name before removing it from the cluster.

Taking a backup of zone file should be fine!

Step 3 : Execute the following cPanel script from the server shell as root user:

/scripts/killdns domain.com

That’s it! Then try to add the domain again. It should be okay now!!

Now, verify this through command line:

cat /var/cpanel/userdata/$user_name/main
