Remove bad block list from Linux MD RAID member disk

The Linux MD RAID driver when it experiences a bad block on one disk will often incorrectly create bad block entries on a second or third disk in RAID5/RAID6 (https://raid.wiki.kernel.org/index.php/The_Badblocks_controversy).

To check if your member disk has any bad blocks recorded on it run:

# mdadm --examine-badblocks /dev/sdd

To clear the bad blocks list on a fully working drive you can run the following commands:

# mdadm /dev/md127 --fail /dev/sdd --remove /dev/sdd --re-add /dev/sdd --update=force-no-bbl
# mdadm /dev/md127 --fail /dev/sdd --remove /dev/sdd --re-add /dev/sdd --update=no-bbl
