There's no explicit message produced by the md module, no.  You need to
check the /sys/block/md{X}/md/mismatch_cnt entry to find out how many
mismatches there are.  Similarly, following a repair this will indicate
how many mismatches it thinks have been fixed (by updating the parity
block to match the data blocks).

I've no idea whether the checkarray script you're using is checking this
counter - there seems little point in having a special script if it
isn't though.

Cheers,
        Robin
