A method begins by a processing module determining, by a first storage unit, that a storage growth rate is unfavorable for the first storage unit over an estimated time frame of reallocating at least a portion of encoded data slices stored in the first storage unit to one or more additional storage units. The method continues with the processing module when the storage growth rate is unfavorable, selecting an unfavorable growth rate abatement approach to include prioritizing new deletes and outgoing allocations such that estimated required storage capacity is less than available storage capacity of the first storage unit for the estimated time frame of the reallocation of the at least a portion of encoded data slices. The method continues with the processing module facilitating implementation of the unfavorable growth rate abatement approach.
