摘要：
A storage processor isolates and classifies file system faults and inconsistencies to produce a fault tree for inline error recovery. The storage processor isolates the metadata objects or objects that have internal inconsistencies, the storage processor creates a fault tree to map the file system; or portion of the file system with the errors or inconsistencies and the metadata objects dependent upon those objects. Once the fault having been mapped, determine the complexity of recovering the branch of the fault tree with the error. If the error is not too complex, performing recovery of the metadata objects online otherwise taking the system offline for file system recovery.
