    Abstract: A method begins by a dispersed storage (DS) processing module determining to remove data object index entries from a data object level index node, identifying data object index entries to extract, and creating a temporary sibling data object level index node to include the identified data object index entries. The method continues with the DS processing module initiating updating of an hierarchical ordered index structure by identifying an address for storing the temporary sibling data object level index node, setting up linking the temporary sibling data object level index node to a next level node and to an adjacent data object level index node, and determining whether a change has occurred. When the change has not occurred, the method continues with the DS processing module removing the data object index entries from the data object level index node and commencing the updating of the hierarchical ordered index structure.

    Abstract: A method begins with a computing device of a dispersed storage network (DSN) determining that an encoded data slice of a set of encoded data slices requires rebuilding and sending partial rebuild requests to storage units of the DSN. The method continues with one of the storage units generating a partial rebuilt slice based one or more encoded data slices of the set of encoded data slices stored by the one of the storage units and securing the partial rebuilt slice using a shared secret scheme that is shared among the storage units to produce a secured partial rebuilt slice. The method continues with the computing device receiving a set of secured partial rebuilt slices from the storage units, recovering a set of partial rebuilt slices from the set of secured partial rebuilt slices, and rebuilding the encoded data slice from the set of partial rebuilt slices.

    Abstract: A dispersed storage (DS) method begins by issuing a plurality of write commands to a plurality of DS storage units. The method continues by receiving a write acknowledgement from one of the plurality of DS storage units to produce a received write acknowledgement. The method continues by issuing a plurality of commit commands to the plurality of DS storage units when a write threshold number of the received write acknowledgements have been received. The method continues by receiving a commit acknowledgement from a DS storage unit of the plurality of DS storage units to produce a received commit acknowledgement. The method continues by issuing a plurality of finalize commands to the plurality of DS storage units when a write threshold number of the received commit acknowledgements have been received.

    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 by a dispersed storage (DS) processing module transmitting a set of write commands for storing a set of encoded data slices in storage units of a dispersed storage network (DSN) and determining whether at least a first threshold number of write responses have been received within a response time period. When the at least the first threshold number of the write responses have been received within the response time period, the method continues with the DS processing module determining whether a total number of responses have been received within another response time period. When the total number of responses have not been received within the other response time period, the method continues with the DS processing module issuing a sub-set of write commit commands corresponding to a response number of encoded data slices for which a response was received.
