Abstract
A method for a dispersed storage network (DSN) begins by receiving a read data object request from for a data object stored as a plurality of sets of encoded data slices in a set of storage units. The method continues by selecting a read threshold number of encoded data slices for retrieval. The method continues by issuing read slice requests to at least some of the storage units of the storage set to recover the selected read threshold number of encoded data slices. The method continues by receiving read slice responses from at least some of the storage units and selecting a decode threshold number of encoded data slices. The method continues by decoding the selected decode threshold number of encoded data slices to reproduce the data and generating audit information based on the selected slices for retrieval, the received slice, and the selected slices for decoding.
