To verify this hypotesis though, you will have to destroy the zpool, use gnop to create a virtual 4k sector drive for each physical drive and try testing everything again, using these new virtual drives. Unfortunately, if this is the case, it will be troublesome to find a production solution just yet. I have an idea but no time to try it.
