Multiple DNSonly servers with multiple cPanel servers -> sync?

Hi,

I have 3 webservers:
webserver 1
webserver 2
webserver 3

They used to work as DNS server as well. I am now moving my nameservers to 3 separate dns only servers:
namerserver 1
namerserver 2
namerserver 3

Right now I have configured it that each webserver writes it's dns to all 3 nameservers.
The nameservers are not syncing with each other. The webservers are also not syncing with each other.

so:
webserver 1 -> namerserver 1,namerserver 2,namerserver 3
webserver 2 -> namerserver 1,namerserver 2,namerserver 3
webserver 3 -> namerserver 1,namerserver 2,namerserver 3

I am wondering if I need to setup sync between the webservers.
I think, with sync between the servers, if I want to transfer accounts between the webservers (which I regularly do), then the records get adjusted right away, and also I don't risk to get any conflicts? Or do I need to sync on nameserver level?

Thanks!

 

Hi,

thanks for the feedback both!

In this configuration, what happens if both webserver 1 and 2 write the same zone towards the dns only's?
If I use the transfer tool in this case (for example server 2 -> server 3), should or should I not use express transfer? And when deleting the account from the old server, should I retain the DNS zone?

Thanks!

 

Hi,

I have now moved to the suggested setup:

webserver 1 -> namerserver 1,namerserver 2,namerserver 3
webserver 2 -> namerserver 1,namerserver 2,namerserver 3
webserver 3 -> namerserver 1,namerserver 2,namerserver 3

However, I still have all DNS zones on all webservers because previously all webserver were syncing to each other. How can I clean up these zones?

Thanks
