摘要： Multiple revisions of an encoded data slice can be stored in a distributed storage unit. Before writing a new revision of an encoded data slice to storage, the distributed storage unit can invoke a write lock for all encoded data slices having the same slice name as the slice being currently written. The slice being currently written can be stored in temporary storage, and a rollback timer started. If a commit command is received before expiration of the rollback timer, the currently written slice can be permanently stored and made accessible for read requests. If the rollback timer expires prior to the storage unit receiving a commit command, however, a previously stored revision will be used.

摘要： A method begins by processing module determining data to migrate, wherein the data is stored as a plurality of sets of encoded data slices in a first set of dispersed storage (DS) units.

摘要： A storage integrity system in a dispersed storage network scans an address range of data slices to identify errors in one of a plurality of encoded data slices, wherein the plurality of encoded data slices are generated from a data segment using an error encoding dispersal function. When the storage integrity system detects an error, it identifies one of the encoded data slices for rebuilding. The identified data slice is rebuilt in response to the type of error. For example, when the type of the error includes a temporary error, the storage integrity system waits a predetermined time period to determine whether the error still exists prior to rebuilding the identified data slice.
