Disk shows Dead. Volume shows fine.
I have X-Raid with dual redundancy configured. A disk failed on me and I went to pull out the bad drive. Stupid me for not checking, but I pulled out disk 6 when disk 4 was the dead drive. I was n...
There's no important data on the swap partition. That's just used for temporarily storing what's normally stored in RAM if the RAM doesn't have sufficient space.
So you can safely do what the error message suggested:
# mdadm --zero-superblock /dev/sdf2
then
# mdadm --manage /dev/md1 --add /dev/sdf2
If sdf2 is marked as a spare in md1 (you can tell this by checking the output of # cat /proc /mdstat ) you can force it to be used properly by doing e.g.
# mdadm --grow /dev/md1 -n6
Have you downloaded the logs and checked those?
I have poked around, but don't know exactly what I am looking at. Here are a couple things. Any suggestions as to what to look for?

I sshed in and ran "smartctl -a /dev/sdf" for Disk 6 and got the following.
Looks like the disk is okay, right?

Sure thing. Here it is.
I have no idea what I am looking at, but md1 says 6/5 and only has 5 Us. Is that a bad thing?
