Mismatch_cnt (/sys/block/md#/md/mismatch_cn
Not much of an issue if this is reported on raid-0 or raid-1 and can be ignored. See bugzilla report: Bug 566828.
The repair is to rebuild the raid:
echo repair >/sys/block/md#/md/sync_actThis does not reset the count, but if you force a check after the rebuild is complete:
echo check >/sys/block/md#/md/sync_actCount should return to zero. Verify with:
cat /sys/block/md#/md/mismatch_cntBookmark/Search this post with
