Abstract: A method begins with a processing module of a distributed storage network (DSN), receiving a request to access a data object stored in the DSN and identifying a first data descriptor associated with the data object, identifying a second data descriptor associated with the data object, identifying a first data index key and a first index structure for the first data descriptor and identifying a second data index key and a second index structure for the second data descriptor. The method continues with the processing module accessing the first index structure for the first data descriptor , based on the first and second data index keys, to retrieve a first and second set of data identifiers, respectively and based on one or more data identifiers being common to the first set of data identifiers and the second set of data identifiers, creating a superset of data identifiers.

Abstract: A computing device includes an interface configured to interface and communicate with a dispersed storage network (DSN), a memory that stores operational instructions, and processing circuitry operably coupled to the interface and to the memory. The processing circuitry is configured to execute the operational instructions to perform various operations and functions. The computing device determines a number storage units that have been provisioned on the storage network but has not been assigned for storage of data. The computing device then determines a storage utilization level for each of a plurality of active storage units associated with the storage network and based on the storage utilization level, determines whether to activate one or more inactive storage units. The computing device is configured to determine at least a portion of the number of inactive storage units for activation and issue an assignment message to the at least a portion of the number of inactive storage units.

Abstract: A processor in a storage network operates by: receiving an access request for a data segment, wherein the data segment is encoded utilizing an error correcting information dispersal algorithm as a set of encoded data slices that are stored in a plurality of storage units of the storage network and wherein each encoded data slice of the set of encoded data slices includes a corresponding checksum of a plurality of checksums; retrieving, from the storage network, a subset of encoded data slices that includes a threshold number of encoded data slices of the set of encoded data slices; determining, based on ones of the plurality of checksums corresponding to the subset of encoded data slices, when the subset of encoded data slices includes at least one corrupted encoded data slice; retrieving from at least one of the plurality of storage units an addition number of encoded data slices required to generate a reconstructed data segment based on the subset of encoded data slices; generating the reconstructed data segment in accordance with the error correcting information dispersal algorithm, using the additional number of encoded data slices and at least some of the subset of encoded data slices; providing the reconstructed data segment in response to the access request; forming a reconstructed set of encoded data slices utilizing the error correcting information dispersal algorithm on the reconstructed data segment; and replacing the at least one corrupted encoded data slice with at least one reconstructed encoded data slice of the reconstructed set of encoded data slices.

Abstract: A method begins with a processing module obtaining a data object from a user and identifying a plurality of virtual storage vaults (VSVs) for storage of the data object. The method continues with the processing module determining dispersal error encoding parameters associated with a first virtual storage vault and error encoding the data object in accordance with those dispersal error encoding parameters to produce a corresponding plurality of sets of encoded data slices (EDSs), issuing write slice requests for the EDSs and receiving EDS information from at least some of the plurality of VSVs. When the EDS information indicates that a threshold number of VSVs have successfully stored the plurality of sets of encoded data slices within a synchronization timeframe, the method continues with the processing module issuing a favorable response to the user, or when a threshold number of VSVs have not successfully stored the plurality of sets of encoded data slices initiating a retry process.

Abstract: A method for execution by a computing device of a storage network includes obtaining storage performance information for a set of storage units of the storage network, where data segments are dispersed storage error encoded into pluralities of sets of encoded data slices in accordance with error encoding parameters that include a pillar width number and a decode threshold number, which is a number of encoded data slices the set of encode data slices is required to reconstruct a data segment of data segments. The method further includes determining, based on the storage performance information and the error encoding parameters, a performance threshold number for a write request to store a set of encoded data slices of the pluralities of sets of encoded data slices in the set of storage units, where the performance threshold number is greater than the decode threshold number and less than the pillar width number.

Abstract: A processing system of a storage network operates by receiving a write request associated with a data object; identifying dispersed storage error encoding parameters; and determining a number of available storage units. When the number of available storage units is determined to exceed a first number, the processing system operates by: determining a first write threshold number in accordance with the dispersed storage error encoding parameters; dispersed error encoding the data object to produce a first write threshold number of encoded data slices; and writing, to available storage units, the first write threshold number of encoded data slices. When the number of available storage units is determined to not exceed the first number, the processing system operates by: determining a second write threshold number in accordance with the dispersed storage error encoding parameters associated, wherein the second write threshold number is less than the first write threshold number; dispersed error encoding the data object to produce a second write threshold number of encoded data slices; and writing, to the available storage units, the second write threshold number of encoded data slices.

The generating includes: generating a first message of the system messages corresponding to a first of the storage nodes based on the system-level message processing parameters, the first message including a first alarm of the alarms having a first priority of the plurality of priorities; and generating a second message of the system messages corresponding to a second of the storage nodes based on the system-level message processing parameters, the second message including a second alarm of the alarms having a second priority of the plurality of priorities. Wherein the system further operates by sending the first message of the system messages in accordance with the first priority; and ending the second message of the system messages in accordance with the second priority.

Abstract: A method includes generating a second encoded data slice of a second subset of encoded data slices of a set of encoded data slices, where the second subset of encoded data slices is not currently stored in a set of storage units of the storage network, where the set of encoded data slices include a first subset of encoded data slices that is stored in the set of storage units and includes at least a decode threshold number of encoded data slices of the set of encoded data slices, and where a first encoded data slice of the first subset requires rebuilding. The method further includes sending the second encoded data slice to the set of storage units for storage therein, where when the second encoded data slice is stored, the second encoded data slice no longer included in the second subset of encoded data slices.
