Abstract: 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.

Abstract: A method begins by generating list range requests. A list range request includes a payload section and a protocol header section. The payload section includes a start slice name field regarding a start slice name of a slice name range; an end slice name field regarding an end slice name of the slice name range; and a maximum response count field regarding a maximum slice name response count. The protocol header includes a payload length field that represents a length of the payload section and an operation code field to indicate the list range request operation. The list range request includes a request to provide a list of slices names corresponding to stored encoded data slices associated with slice names within the slice name range. The method continues by sending the range requests to storage units of the DSN.

Abstract: A distributed storage integrity system in a dispersed storage network includes a scanning agent and a control unit. The scanning agent identifies an encoded data slice that requires rebuilding, wherein the encoded data slice is one of a plurality of encoded data slices generated from a data segment using an error encoding dispersal function. The control unit retrieves at least a number T of encoded data slices needed to reconstruct the data segment based on the error encoding dispersal function. The control unit is operable to reconstruct the data segment from at least the number T of the encoded data slices and generate a rebuilt encoded data slice from the reconstructed data segment. The scanning agent is located in a storage unit and the control unit is located in the storage unit or in a storage integrity processing unit, a dispersed storage processing unit or a dispersed storage managing unit.

Abstract: A method begins a first rebuilder application identifying a data slice having a storage error. The method continues with the first rebuilder application or a second rebuilder application identifying a data segment based on the identified data slice. The method continues with the second rebuilder application identifying one or more other slice servers that are storing other data slices of the encoded data segment. The method continues with the second rebuilder application receiving a sufficient number of the other data slices to reconstruct the data segment and decoding them to reconstruct the data segment. The method continues with the second rebuilder application encoding the reconstructed data segment in accordance with the information dispersal algorithm to produce a new set of data slices and selecting one of them as the rebuild data slice.
