So I'm not sure I did this right. Stupid me, I didn't follow the latest directions. I'm using 9.10.2-U2 (e1497f2).
I have two 4TB drives in a mirror: ada5 and ada3, where ada5 is starting to have unreadable sectors.
I plugged in a new drive which showed up as ada6, then went to the failing drive (ada5) and clicked "replace." The GUI allowed me to select the new drive (ada6) as a replacement. So I selected it. I thought this was what I was supposed to do, because other instructions I recalled reading before I installed the new drive said if the replace command was available on the failing drive, to use that.
Then I had three drives in the mirror all listed as online: ada3, ada5, and new drive ada6. Nothing else seemed to be happening.
So I decided to take failing drive ada5 offline. Then ada5 changed to that funky string of numbers, and it was offline, and the mirror started to resilver. I clicked on the funky string and selected replace, and it was going to let me re-select ada5 as the replacement, and I figured no, that can't be right. Since I suspected the resilvering couldn't happen on an offline drive, I felt it was safe to detach it.
So now I have ada3 and ada6 in the mirror and ada5 is nowhere to be found, which I assume is good? the ZDISK, mirror, and two drives (ada3 and ada6) are online, and the resilvering is continuing. Looks like it's going to take a very long time.
After it's done, I should be OK to shut down the box and remove ada5? Can I then move the new drive over to ada5 (it's a faster port) and FreeNAS will just detect it's over there when I restart?
Thanks for any reassurance....
