spares
ata-ST3000VN007-2AH16M_ZGY6SD1W INUSE currently in use
The spare ZGY6SD1W is in use in mirror-1. The disk it replaced is nowhere to be seen. It is not listed in zdb either. I have another disk to add to the pool, so I can either 1) make the current spare take its place in mirror-1 permanently, and use the new disk as a new spare, or 2), add the new disk to mirror-1, letting ZGY6SD1W go back to being an available spare.
Which doesn't matter to me, but how can I safely progress here? What I've seen from manpages/examples involves issuing replace or detach commands on the faulty drive, but I have no faulty drive to reference here. Running a replace command on the hot spare might get me what I want, but I'd prefer to not try stuff on a live system.
This is zfsonlinux 2.0.5
