check, it went up to 8 in the resync. After the resync, it still is 8. I
haven't ordered a check since the resync completed.
As far as I understand, repair will do the same as check does, but ALSO
will try to fix the problems found. So the number in mismatch_cnt after
a repair will indicate the amount of mismatches found _and fixed_

That is what I thought too (I will have to wait until I get another
mismatch to verify), but FYI--
Yesterday I had 512 mismatches for my swap partition (RAID1) after I ran
the check.
I ran repair.
I catted the mismatch_cnt again, still 512.
I re-ran the check, back to 0.
