Abstract

A method for a storage network, begins by receiving a read data object request from a user device to reproduce a data object, where the data object is dispersed storage error encoded to produce a plurality of sets of encoded data slices that are stored in a storage network storage set and at least a decode threshold number of encoded data slices are required from each set to recover the data object. The method continues by selecting, for each set of encoded data slices of the plurality of sets of encoded data slices, a read threshold number of encoded data slices for retrieval and issuing read slice requests to at least some storage units of the storage set to recover a read threshold number of encoded data slices. The method then continues by receiving read slice responses from at least some storage units in the storage set, selecting, for each received read slice response of a set of the plurality of sets of encoded data slices, a decode threshold number of encoded data slices and for each set of encoded data slices, decoding the selected decode threshold number of encoded data slices to reproduce the data object. Finally, the method continues by sending the reproduced data object and audit information to the user device.
