20130283095 | REBUILDING A DATA REVISION IN A DISPERSED STORAGE NETWORK - A method begins by a processing module identifying a set of encoded data slices that have been created in accordance with a dispersed storage error encoding function having a decode threshold equal to or less than half of a number encoded data slices in the set of encoded data slices. The method continues with the processing module identifying a first sub-set of encoded data slices having a non-current revision level and identifying a second sub-set of encoded data slices having a more-current revision level.

The method continues with the processing module receiving list digest responses from at least some of the set of DS units and determining whether an inconsistency exists between first and second list digest responses of the list digest responses. The method continues with the processing module requesting at least a portion of each of the slice name information lists from first and second DS units of the set of DS units and identifying a slice name information error associated with the inconsistency based on the at least a portion of each of the slices name information lists of the first and second DS units when the inconsistency exists between first and second list digest responses of the list digest responses. | 04-24-2014 |
20140156719 | UTILIZING DATA OBJECT STORAGE TRACKING IN A DISPERSED STORAGE NETWORK - 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. | 06-05-2014 |
20140344318 | Digest Listing Decomposition - 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. | 11-20-2014 |
20140344646 | DISTRIBUTED REBUILDING OF DATA IN A DISPERSED STORAGE NETWORK - A technique of rebuilding data slices in a dispersed storage network when detecting a plurality of data slices that require rebuilding. A plurality of rebuilding resources capable for use to rebuild the plurality of data slices are determined and based on an attribute associated with the determination, a rebuilding task is apportioned and the apportioned tasks are assigned to the plurality of rebuilding resources to rebuild the data slices. The apportionment of the tasks permit more than one rebuilding resource and associated distributed storage unit to perform the rebuild of the data slices. | 11-20-2014 |
20150212887 | REBUILDING A DATA REVISION IN A DISPERSED STORAGE NETWORK - 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. | 07-30-2015 |
