Expanding a pool and other questions.

[KentShades]

So for some reason, I got an alert saying I have some bad disks on my FreeNAS. So I checked it out and my pool was fine and healthy and couldn't figure out why it was complaining. It was saying DA20. So looking at my pool it only went up to DA17. So then looking I see I have 4 disks not doing anything. So my next question is why the hell didn't I used these other 4 disks that are in this device. Is there a limitation to the amount of disks in a pool? Any problems expanding this with the new interface? Just wanting to be cautious here before I do anything. I am considering moving off the data to another NAS and start fresh as well.

Just wondering your guys's thoughts on this. Here is my Zpool manager:

With a 17 disk.

No.

Not that I've heard of.
