Interestingly, we have moved one of our machines in the opposite direction, from Linux 4.2/ZoL 0.6.5.4 to FreeBSD 10.2, because a 12 TB pool under Linux/ZoL was consistently reporting errors every few weeks. The exact same hardware with FreeBSD 10.2 has not been reporting such errors. In our case, drives are all WD RED 6TB. Priyadarshan
