Trying something very similar, but on a production setup, so I don't 
want to mess everything : Can I put a master storage domain into 
maintenance mode, when it contains some running VMs?
Is yes, what will be the effect?
Will it only transfer the master metadata parts to another storage 
domain, or will it also put it into read-only mode or other actions?

Thank you.
