Claim:
1. A method comprises: sending, by a computing device of a dispersed storage network (DSN), a set of check request messages to a set of storage units of the DSN, wherein a first check request message of the set of check request messages includes a first group of slice names that includes a first slice name from each of a plurality of sets of slice names, wherein a plurality of data segments are dispersed storage error encoded into a plurality of sets of encoded data slices, and wherein the plurality of sets of slice names corresponds to the plurality of sets of encoded data slices; receiving, by a first storage unit of the set of storage units, the first check request message; determining, by the first storage unit, a first group of slice information in response to the first check request message; sending, by the first storage unit, a first check response message to the computing device, wherein the first check response message includes the first group of slice information; and interpreting, by the computing device, the first check response message in light of the first group of slice names to identify one or more encoded data slices of the plurality of sets of encoded data slices in need of rebuilding.
