I have just committed a change to the mdadm .git so that mdadm /dev/md4 --fail detached will fail any components of /dev/md4 that appear to be detached (open returns -ENXIO). and mdadm /dev/md4 --remove detached will remove any such devices (that are failed or spare). so mdadm /dev/md4 --fail detached --remove detached will get rid of any detached devices completely, as will mdadm /dev/md4 --fail detached --remove failed though that will also remove any failed devices that don't happen to be detached.
