Due to a bug in the raid-check script, non-zero mismatch counts were reported on RAID 1 arrays, although this could happen legitimately on this type of array. Consequently, the "repair" and "check" commands did not work as expected. The raid-check script has been fixed and now non-zero mismatch counts are no longer reported in the described scenario.

Under certain circumstances, arrays that were always busy when running the raid-check script would never be checked due to a bug in the script. This script has been modified and all RAIDs with active I/0 are checked as expected.
