I just upgraded from older version to 8.3 a few days ago and everything has been working great. I had a zpool with 5 2 TB disks (4 active and 1 spare). It appears this morning that one of the drives has failed. I can see my Volume listed but cannot get a status. Also, I can view 4 disks (3 of which are member of media stripe and 1 is member of media spare), but i cannot access data. Can anyone advise on how to promote the spare to active and if that is the correct course of action? I'm a bit of a noob so looking for some advice so i don't lose my data. Thanks.
