There is a reason why we termed it PosixFS and not SharedFS and that users can specify local devices/FS's (and there is no reason to limit it).
Note that if user defines a local FS and adds 2 hosts to the Posix FS DC then 1 host will be non-op
Why? This makes some very interesting use cases a lot more difficult to set up. We should allow multiple hosts in a PosixFS data center, and it should be the user's responsibility that if he adds multiple hosts, that each of those see the same data.
I *think* we're saying the same thing. If you have multiple hosts in a datacenter with PosixFS then it's your responsibility to make sure that they can all see the same storage
