摘要： A method begins by a dispersed storage (DS) processing obtaining estimated future availability information for storage units and organizing a plurality of sets of encoded data slices into a plurality of group-sets of encoded data slices. For each of the plurality of group-sets of encoded data slices, the method continues with the DS processing module estimating an approximate storage completion time to produce a plurality of approximate storage completion times. The method continues with the DS processing module establishing a time-availability pattern for writing the plurality of group-sets of encoded data slices to the storage units based on the estimated future availability information and the plurality of approximate storage completion times. The method continues with the DS processing module sending the plurality of group-sets of encoded data slices to at least some of the storage units for storage therein in accordance with the time-availability pattern.

摘要： A method begins by storage units of a dispersed storage network (DSN) receiving a retrieval request for a data object, where each storage unit stores a unique group of encoded data slices of the data object and a local set of encoded recovery data slices. The method continues with some storage units sending the unique group of encoded data slices to a requesting computing device and with one storage unit sending an encoded recovery data slice to the requesting computing device. The method continues with the requesting computing device identifying an errant unique group encoded data slice, correcting the errant encoded data slice based on received data slices to produce an updated unique group of encoded data slices, and dispersed storage error decoding the updated unique group of encoded data slices and the unique groups of encoded data slices from other storage units to recover the data object.

摘要： A method begins by a set of storage units of a dispersed storage network (DSN) storing a plurality of encoded data slices, where each storage unit stores a unique sub-set of encoded data slices. The method continues with each storage unit dispersed storage error encoding at least a recovery threshold number of encoded data slices to produce a local set of encoded recovery data slices. In response to a retrieval request, the method continues with a device identifying a storage unit of an initial recovery number of storage units having a rebuilding issue and determining whether the rebuilding issue is correctable at a DSN level. When the rebuilding issue is correctable at the DSN level the method continues with the device selecting another storage unit to replace the storage unit to produce a recovery number of storage units and sending retrieve requests to the recovery number of storage units.

摘要： When an access metric regarding an encoded data object exceeds an access threshold, a method begins by a processing module of a dispersed storage network (DSN) retrieving encoded data slices of a first plurality of sets of encoded data slices and recovering the data object utilizing first dispersed storage error encoding parameters. The method continues with the processing module re-encoding the recovered data object using second dispersed storage error encoding parameters to produce a re-encoded data object, where the re-encoded data object includes a second plurality of sets of encoded data slices. The method continues with the processing module outputting the second plurality of sets of encoded data slices to storage units of the DSN for storage therein and sending a message to retrieving devices of the DSN, where the message indicates use of the second plurality of sets of encoded data slices for the data object.
