Andrew gave you the right answers for all of the above, I just wanted to
add something for this question:

If you use SBD as your stonith mechanism, then the node will suicide if it
loses connectivity to the storage.  Yes, that takes your VMs down hard with
it, but if they reside on the storage and the storage is unavailable,
they're pretty well toast at that point anyhow, no?  The remaining nodes
will notice the dead node and start all of the VMs that went with it
elsewhere.

Mark
