Well, the zpool is blank and I can change the ashift. I guess I'll let it finish :P I was expecting it to take a few hours at the most. I did follow the directions and have everything set correctly. We'll see how this all goes I guess.

I take it you missed [post=43712]post #5[/post].So how long should these tests take?
One full test run on my drives took about 14? hours, give or take a few hours.It took two or three days to run on my old Barracuda 400GB pool (it's okay, laugh).

I'm not sure how I could force a 512byte sector or if I could would the results be helpful at all. If the results will be helpful I can redo the test but I'll need to know how to force a 512byte sector size.

Yeah, I'm going to give up trying to test this zpool. I don't think anyone cares about 512-byte sectors on 4k drives rather than 4k sectors on 512-byte sector drives. So I'll provide results from the other zpool in a week or so when I get the spare drives together.
I wasn't suggesting you should run it.
@noobsauce80, It's the "512e" I mentioned earlier, which Windows had to account for as well.
@jgreco, I think the wording of the option "Force..." isn't coincidental and you describe it correctly. FreeNAS does try to detect, but it gives you the option of forcing it. Since I *DO* have a system with mixed 4k/512-byte drives, I should have used that option when I created my pool (but somehow didn't). But I still look forward to people with 512-byte drives doing the tests both ways because I still say 4k should be the default (even in a mixed drive setup) and that selecting 4k for a 512-byte drive has minimal, if any, negative impact. It also positions the pool well going forward (replacing drives, etc.).
SSH to the box and run:How can I check what block configuration my zpool is using? I couldn't see it through the GUI and don't remember it giving me a choice when I created it.
Did you miss jgreco's [post=46188]earlier post[/post]? Come to think of it you likely already had the test running. Unfortunately, the results as is aren't useful. You should re-read the [post=43638]first post[/post].
