A few days ago I heard some off sounds coming from my NAS box which is under my desk. Thankfully not the "click of death" but certainly sounded like it was trying to re-read the same area of a drive. Having all sorts of drives fail over the years I knew this wasn't a good sound. Opening up the console I see a fairly ominous "Device: /dev/ada2, 1 Current unreadable (pending) sectors" message.
I ran a long test of the drive (attached) and sure enough it is on it's way out. I'm not an expert in analyzing SMART results, but I don't see any good news in there other than maybe "(90% remaining). "
Per the instructions here: https://www.ixsystems.com/community/resources/replacing-a-failed-failing-disk.75/
It seems fairly straightforward to replace the disk, mark it offline, powerdown, replace drive physically, power up, select, click replace button, open beer. I am running an older version (FreeNAS-9.3-STABLE-201604150515) but the instructions appear to apply accordingly.
My questions are as follows (and pretty simple really)
1. I am assuming it is still ONLINE because even though it is having some read errors the disk hasn't completely died (yet).
2. If I replace this disk with a larger one, I won't see any increase in capacity until I replace the other two similarly sized drives in the pool? That is my understanding. TIA
