Have a look at http://www.arrfab.net/blog/?p=199 It says:

A `echo repair >/sys/block/md0/md/sync_action` followed by a `echo check >/sys/block/md0/md/sync_action` seems to have corrected it. Now `cat /sys/block/md0/md/mismatch_cnt` returns 0 …

Thanks. I was trying to figure out how from the mdadm commands (UGH!) to do a scan.

# cat /sys/block/md10/md/mismatch_cnt 8448 # cat /sys/block/md11/md/mismatch_cnt 7296

fugly. Since the mirrors aren't checksummed, can i assume this means there's likely some data messups here?

Anyways, the repair is running on both md10 and md11, i'll check back with my final results...
