Sounds awfully complicated to me. Perhaps this is how it internally
works, but my 2 cents go to the option to gracefully remove a device
(migrating to a spare without losing redundancy) in the kernel (or
mdadm).

I'm thinking

mdadm /dev/raid-device -a /dev/new-disk
mdadm /dev/raid-device --graceful-remove /dev/failing-disk

also hopefully a path to do this instead of kicking (multiple) disks
when bad blocks occur.
