9 is the major number and 2 the minor which I believe corresponds to /dev/md3

The md device should never through a disk error at you unless you are 
running a non-raid level. Ie. linear or raid 0.

If the md device is ok according to /proc/mdstat the filesystem is borked 
and should be fixed. Depending on how large it is this might take a few hours.

Or a bad cable. Quite likely. Check the cables, repair the fs.


I don't make sense, I don't pretend to either. Questions?
