Hi All,
I'm having a little trouble understanding the hot spare in my FreeNAS 11.2-U6 server. I installed one a few months ago as I had a drive on hand and space in my server. The pool is a RaidZ2 with 6 x 4TB WD Reds plus another WD Red 4TB as a hot spare. I woke up this morning to an alert that says the following:
Device: /dev/ada5, Self-Test Log error count increased from 0 to 1
Since the drive hasn't straight up failed yet, I think I get why the hot spare didn't take over. I offlined the drive that had the errors, but the spare doesn't seem to be taking over. Do I need to physically remove the offlined drive for the hot spare to kick in? I wanted to get some clarification before I do that. I also tried replacing the offline drive, but the only drive I can replace it with it itself. The hot spare doesn't show up in the list. At this point would it be easier to just remove the spare from the pool and replace the failing drive?
If this is the case, I'm not sure what the hot spare is good for, unless you had a drive completely disappear.
Here's the output from zpool status:
Any help or other suggestions would be greatly appreciated.
Thanks in advance!
