A method for updating storage resources in a dispersed storage network operates to determine a storage utilization factor for a storage pool that includes a set of storage resources when old storage resources are being reallocated to new storage resources. The method continues by denying write type requests during reallocation when the storage utilization factor is at or above a threshold and processing write type requests when the storage utilization factor is at or below the threshold. When the reallocation is complete the storage utilization factor is recalculated.

Managing storage resources in a dispersed storage network

A method for execution by one or more processing modules of one or more computing devices of a dispersed storage network (DSN), the method begins by determining, in advance of a DSN data access request, an optimal routing configuration for the DSN data access request to a collection of one or more DS processing units. The method continues by assigning a final destination identifier (FDI) to the collection of one or more DS processing units. The method continues by associating a request router with the collection of one or more DS processing units and distributing the optimal routing configuration to each of the collection of one or more DS processing units and to the associated request router. The method continues by receiving, by the associated request router, a request to access DSN data located in a DSN memory, wherein the request includes at least the FDI and routing, by the request router, the DSN data access request to the collection of one or more DS processing units according to the optimal routing configuration. The DS processing units will then process the DSN data access request for a storage unit where the data is stored (read) or is to be stored (write).
