+1.
I believe that Ayal didn't mean that we should limit the number of
Hosts in a PosixFS DC to 1; all he said is that in case the user has
defined more than 1 Host in a PosixFS DC and the PosixFS storage
domain in it happens to be a local one (i.e. local on one of the
Hosts in the DC), all other Hosts will become Non Operational
(simply because they won't be able to reach that storage domain).
Correct. It was a disclaimer that we do not prevent user from doing stupid things.
