A patch series for that bug was submitted for review. [1]

The fix was tested over several weeks on two production machines. I
encourage all MD array users to adopt the new md-array-device-mapping

The checkarray script was ported but is still in testing. [2] It will

Thanks everyone, and please have a good weekend!

Kind regards
