I saw this the other day when doing an initial "auto sync" from one Nexenta
3.0.3 node to another (using the ZFS/SSH method). I later tried it again with a
fresh destination pool and the read traffic was minimal. Sadly I didn't have an
opportunity to do and investigation, but it doesn't fit my current model if how
things do or should work (which is troubling).
