Abstract
A method begins by a dispersed storage (DS) processing module of a dispersed storage network (DSN) obtaining status information from a set of distributed storage units (SUs) and determining that a plurality of the SUs are currently inactive. The method continues with the DS processing module selecting one or more inactive SUs for reactivation and issuing a request to change activation status to each. When a favorable response is received from the one more SUs, the method continues with the DDS processing module determining that encoded data slices (EDSs) stored in a first SU include errors and determining to rebuild the EDSs stored in the first SU that include one or more errors by issuing a request to change activation status to second SU that is currently inactive. Upon receiving a favorable response from the second SU, the EDSs with errors are rebuilt using EDSs from the second SU.
