[Cluster] Add Server
 

Hey,
assuming I have an up & running system with lots of clients/data, when I add a new Storage/DB, is the data replicated/synced automatically?

Hello.
If You used our node installer, then Storage/DB synchronization/replication will start automatically, else You should configure it manually.

thanks,
is there a way to later convert a save into master?

Master and slave storage serves have their own IP addresses. Nevertheless, there is a "floating" IP address. This IP is assigned to the current master storage. Almost all operations with a storage server are performed via the "floating" IP. In the case of falling the master node, it's place is automatically replaced with a slave node and the "floating" IP will be assigned to it.
