Abstract
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.
