> The main problem is that localAllocation does not find next lowest volume.
> and it will assign to remote in rack.
> We should control the remote tasks.
> * Leaf scheduling priorities
> 1. tasks in a volume of host
> 2. unknown disk, non-splitable in local host
> 3. remote tasks in rack. (consider the remaining tasks)
> 4. random remote tasks. (tail concurrency control of scheduled tasks)
