METHOD FOR REAL-TIME REPAIR OF FILE SYSTEM AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To enable real-time correction of corruptions of a file system. SOLUTION: The file system enables the real-time correction of detected corruptions to on-disk data. An enhancement function to a file system responds in real time to file system corruptions detected on a running volume and repairs the corruptions at the point where the file system detects them. Upon detection of a corruption by the file system, the system enhancement function records information describing the nature of the corruption. A repair scan is defined for each type of corruption encountered. Repair scans can be run at the top level of execution in the current thread in which the corruption is detected or they may require a dedicated thread to perform the repair processing.
