Narrative:

En route over cleveland, lost all hydraulic system #2 fluid. This resulted only in loss of partial ground lift dumping and inboard brakes. Per QRH, diverted to cmh. By the time we got hydraulic low caution, fluid was already gone. Cmh was decided to be diversion when factoring in descent. Several leaks were found in hydraulic system #2. Perhaps accumulator on all hydraulic controls would allow extra use of system that are dependent on one system.
