Ceph becomes unresponsive when one node-mon goes down

[wjvanzyl0]

I have 2 ceph nodes. Each has a mon and mgr installed. Whenever I shutdown any one mon-instance on any of my nodes ceph becomes completely unresponsive until I start that mon again. Is this normal or can I fix this?

You cannot run just two nodes, three is the absolute minimum.
