Storing data in accordance with encoded data slice revision levels in a storage network

Abstract:

A method includes receiving, by a storage unit of a set of storage units of a storage network, a write request of a set of write requests that includes a first group of slice payloads for first encoded data slices of each set of a plurality of sets of encoded data slices and a corresponding revision level. The method includes processing, by the storage unit, the write request by determining whether the corresponding revision level of each of the first encoded data slices is a next revision level and generating a write response message that includes a group of status messages for the first encoded data slices based on the determining whether the corresponding revision level of each of the first encoded data slices is the next revision level. The method continues by sending the write response message to a computing device of the storage network.
