Sorry, that didn't work unfortunately. I had to wait a bit until I could 
do it between it trying to resilver and workload. It came online at 
first, but then went back to removed when I checked again later.

Any other diags I can do? I've already run smartctl on all the drives 
(5hrs+) and they've come back clean. There's not much to go on in the 
logs either. Do a small number of drives just naturally error when 
placed in a raid or something?
