Maybe would be useful to have unrecoverable read errors on degraded

I think if you set it to readonly mode, it wouldn't degrade further
even on read error.
I think I saw this from the source code, but now I'm not really sure
any more.
Do you want to check?
I had by sure to recreate the degraded array some times because of going
down while reading from defective sectors.
I'm not sure if always I set array to readonly (because I was quite in
panic) ... but I'd guess I did.
I'll try to look into the code.
This has been my first bad experience with raid, I never had to go deep
inside maintenance mode or to look into source code .. but I had to
learn fast ;-)
