If there is a bug here, I'm not sure people will see it for a while in practice. I mean, who is using hardware raid to create a 8.5GB "disk" then create a zpool with that one "disk"?

You mean 8.5TB. Believe it or not,

a) You can buy 1 TB drives off the shelf so you need only 8 or 9 of them to reach that capacity, and 9 drives is a trivially small number in serious installations. b) Hardware RAIDs can be useful in some situations because they automagically handle certain situations like hot-plugging (including rebuilding) and reporting (audio-visual signs). c) "Hardware" RAIDs might not be DAS but also iSCSI or fibre channel, in which case it's useless and harmful (to performance) to do software RAID on them.

Both hardware and software RAIDs have their uses, but the issue in this thread is to discover which component (if any) has a bug that makes the original configuration tried by the OP unusable.
