1. A method comprises: sending, by a first device of a dispersed storage network (DSN), a set of write revision requests to storage units of the DSN, wherein a write revision request of the set of write revision requests includes a slice name and a revision number corresponding to a revision level of a revised encoded data slice; generating, by one of the storage units, a write revision response regarding a potential write conflict issue based on the revision number; receiving, by the first device, the write revision responses from at least some of the storage units to produce a set of received write revision responses; interpreting, by the first device, the set of received write revision responses to determine whether a write conflict issue exists; when the write conflict issue exists, issuing, by the first device, a set of write roll back requests to the storage units regarding aborting storage of respective revised encoded data slices; and when the write conflict issue does not exist, issuing, by the first device, a set of next phase write requests to the storage units regarding storing the respective revised encoded data slices.
