mdstat shows quite well that all the disks are on line, or not, it is simple and effective IMHO.
When you mount one side of the mirror you may actually be corrupting it.....possibly preventing it being written to.
If you are going to do that, go to single user mode, unmount the mirror device, mount one/both sides in read only mode and look at the files.
I must admit this is novel, I have never come across someone not trusting a mirror before....

Thing

mdadm -D /dev/md0 diplays information dating back to when the raid
array was created. cat /proc/mdstat doesn't give much detail in my
opinion.
how can i find out the current health of the array and whether or
not files on the mirror are being correctly updated, i.e., if i mount
the mirror partition, i do not see that particular files have been
updated.
