Thanks. I was trying to figure out how from the mdadm commands (UGH!)
to do a scan.
# cat /sys/block/md10/md/mismatch_cnt
# cat /sys/block/md11/md/mismatch_cnt
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...
