 Now, today, I wanted to determine which disk was failing, so I

Just to be sure - did you do that on live array ? (it kinda looks like you did)


Below the first command, and separated by ten hyphens is --detail
/dev/md0 which shows that the remaining device is marked "removed" and
not "failed".

I thank you for your help thusfar - You've allowed me to mount the
array and access my data. However, I would very much like to get my
RAID 5 back to non-degraded status ASAP.


You can add the drive/partition with --add option to the existing array.

It will start rebuilding then, and it can take a while.
