I originally posted this on /linux, but got nothing - if there is a better subbedit, let me know!
Friday the 13th started off with a bang for me! I've got two drives on my raid5 reporting a failure - mdadm has already automatically removed one apparentlty, and the other one is reading "faulty spare rebuilding". The problem is that mdadm still has the spare listed:

Am I totally and utterly screwed?
