    Abstract: A method for execution by a computing device of a storage network begins by receiving a write request for a data object, determining a plurality of data regions for the data object, determining storage identification information for each data region of the plurality of data regions and generating a storage table for the data object that includes information sufficient to identify each data region of the plurality of data regions. For a first data region of the plurality of data regions the method continues by dividing the first data region into a plurality of data segments, and dispersed error encoding the plurality of data segments to produce a plurality of sets of encoded data slices. The method then continues by sending a write request for each encoded data slice of each set of encoded data slices of the plurality of sets of encoded data slices to the storage network, and when at least a write threshold number of write responses is received for each of the plurality of sets of encoded data slices the method ends by updating the storage table to indicate that the first data region is available for retrieval.

    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 method for execution by a distributed storage (DS) unit of a dispersed storage network (DSN), includes receiving a set of write slice requests that includes a set of slice names that are not utilized to store encoded data slices (EDSs), where each write slice request from the set of slice names that are not utilized to store encoded data slices includes a trap slice. The method continues with an access slice request that includes a requested slice name being received from a second DSN client, and then continues by determining whether the requested slice name corresponds to a trap slice stored by the DS unit. When the requested slice name corresponds to a trap slice, an action is determined for the access slice request based on an anomaly processing scheme.

    Abstract: A method includes identifying an existing logical storage vault having existing dispersed storage coding properties for vault transformation, where a first set of storage units support the existing logical storage vault, and a data object of first data objects stored within the first set of storage units is stored as a first plurality of sets of encoded data slices in accordance with the existing dispersed storage coding properties. The method includes identifying a new logical storage vault having new dispersed storage coding properties, wherein storage units support the new logical storage vault. The method includes transforming the first data objects from being in accordance with the existing dispersed storage coding properties to being in accordance with the new dispersed storage coding properties to produce transformed first data objects. The method includes storing the transformed first data objects in the new logical storage vault supported by the storage units.
