I have an array of 16x3TB drives, including 2 parity.
I currently have 2 drives giving me a SMART error. 1 parity and 1 data. The exact error is: "End-to-End Error, Failing now" with a count of 1 in Attributes.
First of all, is it fair to assume that I should decommission those drives now?
Second, what's the best way to do that? Many of my data drives are still empty, so I'd like to move the data from the failing data drive to an empty drive, and hopefully move the parity drive to another disk without rebuilding parity.
Here are my assumptions. Maybe I'm wrong.
- I can just `mv` files from /mnt/disk5 (failing) to /mnt/disk10 (new, empty) then remove disk5 from my array.
- There is no way to move my parity drive without rebuilding parity. I'd have to decommission my failing parity drive, then assign parity to a new drive, then rebuild. I'm hoping for a way to avoid rebuild!
What'd be the best way to proceed?
Thanks!
