On my master node of the 2-node PowerDNS cluster I have in my test environment to find all ins-and outs to deploy to production im getting the following error in the logs:
Request to queue notification for domain 'domain.example' was processed, but no valid nameservers or ALSO-NOTIFYs found. Not notifying!
This has something to do with the NS / A records on that domain only I cannot find what I have to do at this point, seems that my configurations are correct.
Master config:
allow-axfr-ips=10.10.30.32
master=yes
slave=no
Slave config:
allow-axfr-ips=10.10.30.31
master=no
slave=yes
On the slave node I also added the following record in the database:
MariaDB [powerdns]> select * from supermasters;
+-------------+--------------------+---------+
| ip | nameserver | account |
+-------------+--------------------+---------+
| 10.10.30.31 | ns2.domain.example | admin |
+-------------+--------------------+---------+
I personally think it has something to do with the database, as I read in the documentation:
• The nameservers have to be set up correctly as NS domain records i.e. defining a NS and A record for eachslave.
• Master/Slave state has to be configured on a per domain basis in the domains table. Namely the type column has to be either MASTER or SLAVE respectively and the slave needs a comma separated list of master node IP addresses in the master column in the domains table.
But I do just not understand what it's trying to say. Anybody an idea?
EDIT:
On my slave server there was a faulty record in the domains table, which led the slave to send the request to the wrong server like this:
Apr 8 08:56:03 hfr-nl-dns02 pdns_server[2582]: While checking domain freshness: Query to '10.10.30.32' for SOA of 'ns2.domain.example.' did not return a SOA
Apr 8 09:02:12 hfr-nl-dns02 pdns_server[2582]: message repeated 3 times: [ While checking domain freshness: Query to '10.10.30.32' for SOA of 'ns2.domain.example.' did not return a SOA]
After I changed the ip to .31 I got the following errors:
Master:

EDIT 2: master database records, seen with the IP here, tried it also with the hostname of the nameservers which are defined in the /etc/hosts file.
