MAAS controller Error: Mount the root '/' filesystem to be able to deploy this node

@Dragnell87, I’m not sure how to piece together an answer from what you’ve said so far. I noted there’s an error at the top of the screen, saying that storage can’t be modified unless the machine is in a ready or allocated state. I’d really like to know what state this machine was in when you received this error. I need to get more information from you – can you send log files, etc? You can use this guide to help you see what it is that we probably need.
