Ok, think I have the biggest issue. The drives are 4k sector drives, and I wasn't aware of that. My fault, I should have checked this. Had the disks for ages and are sub 1TB so had the idea that they wouldn't be 4k drives... I will obviously have to address this, either by creating a pool

[zfs-discuss] L2ARC - shared or associated with a pool?
