I have a mirror comprised of two vdev's, recently resilvered from two failed drives. One of the failed drives I detach'd with no problem but the other died and the BIOS wouldn't see it at boot time. I physically removed it and now have only the two new drives installed but I can't detach this old "ghost".
Note (if it makes a difference) these are geli-encrypted drives. I'm not sure where to go from here. Thanks for any help you guys can provide.
