Claim One:
1. A method comprises: sending, by a computing device of a dispersed storage network (DSN), a slice name request to a set of storage units of the DSN regarding a set of encoded data slices, wherein a first storage unit of the set of storage units stores, or is assigned to store, a first encoded data slice of the set of encoded data slices, wherein each encoded data slice of the set of encoded data slices has a unique slice name that includes a unique pillar number and common slice name information; determining, by each of at least some storage units of the set of storage units, a slice name response for a corresponding encoded data slice of the set of encoded data slices, the slice name response includes a slice name for the corresponding encoded data slice and revision number information of the corresponding encoded data slice; receiving, by the computing device, the slice name responses from the at least some storage units; determining, by the computing device, whether one of the slice name responses has different revision number information than other responses of the slice name responses; when the one of the slice name responses has different revision number information than the other responses of the slice name responses, adding the slice name of the one of the slice name responses to a revision mailbox for rebuilding of the corresponding encoded data slice of the set of encoded data slices identified by the slice name; and rebuilding, by a revision agent, the corresponding encoded data slice identified in the revision mailbox.
