摘要：
A storage processor includes storage for redundantly storing a log file of a journaling file system on a separate logical device from a primary copy of the log file and further provides for recovery of the file system upon failure of both the primary storage and the redundant storage storing the log file of the journaling file system by storing dirtied metadata objects in the cache of the storage processor to a vault area and then applying the stored dirtied metadata objects against the underlying persistent storage.
