Narrative:

During climb through 13000 ft accelerating to target climb speed; a noise was heard. The noise was determined to be located aft of first class in the cargo area of the aircraft. The captain made a call to the flight attendants to discuss the origin and cause of the incident. The captain requested the relief pilot to check the cabin for any unusual noise or vibration. None was reported to us. We then made a call to dispatch and maintenance. The captain requested information regarding cargo compartments and write-ups regarding container locks. We were told there were 2 containers missing and no reported lock failures. We discussed the noise; location and possible causes. There were no secondary system failures; fluid loss or vibration observed or reported by anyone during flight. We concluded the cause of the noise to be a container shift with the information at hand. We made the decision to continue to lfpg. After the initial call to the flight attendant; there were no further calls or conversations regarding any vibrations or unusual noise from the flight attendant or passenger during the entire flight to lfpg. After arriving at the gate at lfpg; we were informed of the missing pack access door. Maintenance was informed and an aml entry was made.
