PowerDNS topology
 

Hi Everyone,

I've successfully installed PowerDNS like this:

1 Super Master with a separate MySQL database (Backend). This server notifies the 02 slaves with changes in domains.
2 Slaves with local MySQL.

Is it possible to add a 2nd Super Master that has the same role (notifies the 02 existing slaves).
a- I don't know if I can use the existing MySQL database for both Super Masters, or should I create a separate one?
b- If I have to create a separate database for 2nd Super Master, how can I sync the data between the 02 databases of Super Masters (Without MySQL replication).

Thank you in advance.
:D
