Running 8.0-RELEASE-p1 with ZFS version 13. I recently swapped out motherboards on my NAS which appears to have broken my zpool (known as 'bigpool'). As you can see below, zfs thinks there are 2 drives named ad6 which makes it think something is corrupted. If you'll notice, also, that the two drives are mounted to the same path. That, is the problem. Somehow, ad10 is being mounted to /dev/ad6 (I think. I'm not even sure if I've diagnosed this correctly). If I unplug ad6, a zpool status shows 'disconnected' and ad10 appears on the list. If I unplug ad10, nothing changes. I have no idea why. More importantly, I have no idea how to fix that. I don't know of any fstab for zfs. Any idea what's up or how to fix this?
