摘要： A method begins by a processing module storing a set of encoded data slices in storage units. A data segment of data is encoded, in accordance with dispersed storage error encoding parameters, to produce the set of encoded data slices. The dispersed storage error encoding parameters include a decode threshold number and a pillar width number, which is at least twice the decode threshold number. The method continues with the processing module processing a first request for retrieval of the data segment by retrieving a first sub-set of encoded data slices, which includes the decode threshold number, and decoding them to produce a first recovered data segment. The method continues with the processing module processing a second request for retrieval of the data segment by retrieving a second sub-set of encoded data slices, which includes the decode threshold number, and decoding them to produce a second recovered data segment.

摘要： A method begins by a dispersed storage (DS) processing module dividing a very large data object into a plurality of data regions and generating a data object storage tracking table that includes sections for identifying one or more data regions that are available or unavailable for retrieval. The method continues with the DS processing module dividing a first data region into data segments and disperse storage error encoding the data segments to produce sets of encoded data slices. The method continues with the DS processing module sending DSN write requests regarding storing the sets of encoded data slices to storage units and when at least a write threshold number of write responses is received for each of the sets of encoded data slices, updating the data object storage tracking table to indicate that the first data region is available for retrieval.

摘要： A method begins with a processing module determining a retrieval threshold for retrieving a set of encoded data slices from a dispersed storage network (DSN). The set of encoded data slices represents data encoded using a dispersed storage error encoding function having a number of encoded data slices in the set of encoded data slices equal to or greater than a decode threshold and the retrieval threshold is equal to or greater than the decode threshold. The method continues with the processing module issuing data retrieval requests to the DSN for the set of encoded data slices and receiving encoded data slices of the set of encoded data slices to produce received encoded data slices. The method continues with the processing module decoding the received encoded data slices to recapture the data when a number of received encoded data slices compares favorably to the retrieval threshold.

摘要： A method begins by a dispersed storage (DS) processing module of a storage unit receiving a write request for storing a data object that includes updated access control list (ACL) information. The method continues with the DS processing module determining whether the data object is a new data object or a revised version of an existing data object and determining write authority of the requesting entity based on information contained in a locally stored access control list. When the write request is regarding the revised version of the existing data object and the write authority includes authorization to issue the write request for the revised version of the existing data object and authorization to issue the updated ACL information, the method continues with the DS processing module storing the revised version of the existing data object and updating the access control list based on the updated ACL information.

摘要： To identify slice errors, a processing module of a computing device in a dispersed storage network (DSN) sends first list digest requests to at least first and second dispersed storage (DS) units. The requests indicates a first range of slice names to include in a first list digest. The processing module receives digest responses from the DS units, and compares the digest responses to determine whether they identify the same slices. If they do not identify the same slices, the processing module sends second list digest requests indicating a sub-range of the first range of slice names to include in second list digests. The sub-range continues to be narrowed until the processing module identifies at least one sub-range of slice names where a slice error exists.
