I am working with "Arno Fuel SR1" and I want to create a environment with one controller node and one compute node. However, whenever I create an environment, it is "Deployment Mode:Multi node with HA". I could not find a menu to create "Deployment Mode:Multi node". In previous version of Arno Fuel (1.0), there was a menu to do it. Would you know how to create "Deployment Mode:Multi node"?
