Abstract: A distributed storage system receives a file from a client, stores the file into different storage units in the system, creates a system log in an access entry and creates a unit log in each storage unit. The system log records information of all files stored in the system, and the unit log in each storage unit records information of all files stored in the storage unit. When a file stored in a first storage unit is lost or destroyed, the system determines a second storage unit that stores the same file as the first storage unit according to the information recorded in the system log and the unit logs, and repairs the file in the first storage unit by copying the same file from the second storage unit to the first storage unit.
