> Currently Mover logic may move blocks to any DN which had target storage
> type. But if the src DN has target storage type then mover can give highest
> priority to local DN. If local DN does not contains target storage type, then
> it can assign to any DN as the current logic does.
> This is a thought, have not go through the code fully yet.
> Thoughts?
