Help understanding SMART message & replace drive procedure
Posted: 27 Mar 2014 23:31
I started getting errors from one of my two drives. Both are 3TB mirrored in a pool using ZFS. The error And version of nas4free is NAS4Free 9.1.0.1 - Sandstorm
I keep backup of the drive but now I'm trying to understand what the problem is and how soon the drive will fail. I won't be able to replace the drive before the weekend at the earliest. In addition, I've never had to replace a drive using a ZFS pool so I'd appreciate if someone could suggest some search terms so I can find and learn about how to do this. If I get confused I'll ask but I try to learn myself first.
The other drive is the same brand and it shows PASSED but has this read failure that has me worried too.. The failing drive (below) shows 90%.
SMART drive info for failing drive is below. There are two errors and I don't know what they mean and if this is something that is fixable or if the drive is trashed.
thanks in advance for any help!
