4.102. mdadm

Updated mdadm packages that fix two bugs are now available for Red Hat Enterprise Linux 5.
The mdadm packages contain a utility for creating, managing, and monitoring Linux MD (multiple disk) devices.

Bug Fixes

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.
All mdadm users are advised to upgrade to these updated packages, which fix these bugs.
