Yes. You have single drive redundancy. I generally have a spare drive
installed to take over as soon as there's a failure, *just* in case.

Yep. Replace the faulty one, then everything comes back and you get to watch
the funky /proc/mdstat "animation".

Bad, bad, bad. :-)

If I cared enough to set up RAID, I'd care enough to remove any drive that
even hinted at failure... :-)
