> 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?
