Cluster slave servers for DNS replication problems

SYSTEM INFORMATION
OS type and version Debian 12
Virtualmin version 7.50

I have noticed a problem with cluster slave servers for DNS. I have created a cluster with NS1 as master, ns2 and ns3 as slaves. Initially it was only ns1 and ns2, I have added ns3 about a month ago. Never check them, as they seemed to work. Upon adding ns3 I have notice a problem with dns validation tools and started to investigate what is going on. It seems that on both ns2 and ns3 all the the zones where created, but on the ns2 3 of them are empty and where never updated and some of the other zones where updated this morning with an older version than it is on the ns1. I know that, because on Friday I have updated all zones to have 3 name servers instead of 2, so it should have replicated by now. On ns3, only 3 zones have updated. The rest are blank and show never updated.

My question is how much of this process is controlled by Virtualmin and how much is controlled by BIND, before start braking things :slight_smile:

Solved and I’m not sure it is a feature or a bug în Virtualmin configuration. The zones on ns2 and ns3 were created some with root rights, some with bind rights so bind couldn’t manage all of them, but only those created with bind rights. Again, not sure how the scrips works, I let Virtualmin manage master/slave relation, I only ticked the right checks in Virtualmin interface.
