I had the same challenge and ended up taking the service off my hosted-engine and putting it elsewhere as a workaround.
But if I remember right you can still set maintenance mode when the hosted-engine is down, just can't run vm-status?

this cant be the answer. Maybe NFS is the wrong tool for the wrong purpose in this case then.
I am talking about disaster recovery, but you only have "soft" failures in mind.
