Subject Re: distributed database

Are there instructions on how to do it either way?  If I have 4 nodes
running a database and want to add a node, wouldn't I need to spin up 5
more nodes and then replicate the contents over from the first 4 nodes?
 That seems really intensive and painful if not using virtualized hardware.
