            Assignee: Sammi Chen


During Container replication, Replication manager is responsible for choose the 
DN to place the new replica.  When a DN is choose, it's total remaning space is 
compared with the container used bytes.  This will cause write problem when the 
DN total remaning space is greater than container used bytes, while none of the 
volumes of DN has enough space to hold the new container replica.
