Powerdns has a very nifty tool to import BIND zone files into its database.
It has a problem though, your slaves won’t receive these new zones.
This happens because the zones are inserted as type “Native”, which means that you have to rely on SQL replication or some other way to transfer your new data to the slaves.
Luckily, the fix is rather easy, the following example uses MySQL.
Go to your master server and convert all domains to type MASTER so that pdns will start to notify its slaves about this fabolous happening.
Assuming your master database is called “powerdns-master”:
update `powerdns-master`.domains set type = ‘MASTER’
Now wait a few seconds or minutes and your slaves will recieve notifcations!
