[Pdns-users] How-to synchronise several master ?

[AJ McKee]

Hey Arty,

The easiest way to do this is select one of the servers to act as master
for all of the network. The when you do an update on the master, the
slaves will be notified and updates occur.

However if you can't do this, as of present well then there is an even
easier way. Since you are using MySQL already, you can set up a master
SQL server and replicate the changes out to the rest. So when you update
the db on the master, the changes are replicated out to the rest of the
servers. 

Or you could setup a multimaster site replication type scenario with
MySQL, although I have never done this so can't help ya there.
