I should have say replica 3+arbiter when adding the 3rd host. Yes i know that the documentation specified 3 hosts. But if i understand this is to make sure the system is always reliable and that make sense. But my questions is mainly is it possible to start with 2 nodes and had a 3rd one later..when i had the budget. If i am not mistaking Gluster can work with 2 nodes.
