getting to 4K disk blocks in ZFS

And what does camcontrol report for that?

I'm gonna guess that identify doesn't work as areca's typically don't
implement passthrough support, but would be insterested to confirm.

I really need to add the fact that it is on a Areca controller, other it
does not show.
(The 3ware was the server before that)
