摘要： A file system allows a different checksum algorithm to be used for different extents of a file system object independently of other extents of the file system object. The checksum algorithm can be a selectable attribute of an extent or range of extents of a file system object, such that some extents of a file system object can use a first checksum algorithm, while other extents of the file system object can use a second checksum algorithm. An extent of the file system object also may have no associated checksum algorithm. The file system stores, for each extent of a file system object, data indicating a checksum for the extent and an indication of any checksum algorithm used for the extent.

摘要： A file system can allocate data of a storage system into data units, wherein a set of data units can be grouped into a storage region within a volume. A process of verifying validity of data within a storage region can include obtaining a first set of error-detecting codes from a subset of the data stored in a storage system, such as from a data unit of a file system object. Each of the first set of error-detecting codes can be associated with a corresponding data unit within the storage region. A second set of error-detecting codes can be generated based at least in part on the first set of error-detecting codes, and the second set of error-detecting codes can be associated with the storage region so that the second set of error-detecting codes can be used to verify the validity of the data within the storage region.
