   Well, what we need is to fence a failed node, so it's better to break some virtualization
processes than to reboot the whole host that might be carrying a lot of other working guests
on other primary storages. That exactly was what I had a day before I proposed the change
we're discussing.
   
   As an alternative, we can add some blocking rule in iptables that will make the NFS-target
totally unreachable (to make sure that the host could not write anything there).
