DaggyStyle,
Do you want to check it and report or just fix it, if you can?
| Code: | | echo check > /sys/block/md0/md/sync_action |
will start a check on md0.
After the check completes, | Code: | | cat /sys/block/md0/md/mismatch_cnt |
will be a count of the problems, which should be zero.
Change check to repair, if you really want a repair.
However, that calculates the redundant data from the elements that can be read.
What do you really need to do?
