Ejabberd Cluster Connection lost Split Brain

Hi,

I´m currently running an ejabberd-cluster, all works great at the moment.
My question is when a split brain (connection between the nodes is lost) situation oocurs, is there a way that the two nodes will find again each other, and is there a way that the databases are being synchronized again. Or will I have to use one DB as a Master to synchronize the other DB with?

Thanks in advance

best regards

Alex
