Systems and methods for allowing incremental journaling

摘要

In one embodiment, systems and methods are provided for incremental journaling. In one embodiment, order-independent operations are journaled incrementally for the same storage location. In one embodiment, partially ordered operations are journaled incrementally for the same storage location. In one embodiment, order-independent operations and partially ordered operations are journaled incrementally for the same storage location. In one embodiment, incremental journaling is used to update data that represents accounting, ctime, and parity.
