Not sure about this but I thought this would be possible by using mdadm
in monitor mode? In the manpage of mdadm it says:

   As  well  as  reporting  events,  mdadm may move a spare drive from one
   array to another if they are in the same spare-group and if the  desti-
   nation array has a failed drive but not spares.

But I don't know how to create a spare-groupi or what is meant by it?
