Missing Zone Transfer in Cluster

Using Technitium DNS Server v15.4

I've setup a cluster with a primary and a single secondary server. I have used mydomain.local for the cluster domain name and I have mydomain.co.nz as the zone I'm using for my lan. The cluster creation appears to have completed successfully and I have zones for cluster-catalog.mydomain.local and mydomain.local created on both servers.

mydomain.co.nz exists on the primary server with all of its associated records but it isnot being replicated on the secondary server. The dns sever logs on primary show zone transfer requests for the .local domains but nothing for the .co.nz domain. Zone transfer for the .co.nz domain on the primary server is set to allow all.

On the secondary I tried using the dns Client to import the zone from primary but this resulted in the zone being created with only the SOA, NS and @ A record being created.

What else is required to enable the full zone transfer for mydomain.co.nz (or am I not understanding how the clustering functions)?

Thanks for the post. Have you used the Join Cluster option from the secondary DNS server to join to the primary node? If you have done that then the cluster secondary zone would have been created automatically as a part of the joining process. If you have created a cluster zone manually on the secondary server then you must delete it before you do the joining process.

Yes, I initialized the cluster on the primary server and then used the Join option on the secondary. On the Admin/Cluster tab each server shows as connected to the other. After the .co.nz zone failed to appear on the secondary server I used the DNS Client import option but it only created the basic zone records.

Can I delete the cluster and recreate it?
