Abstract

See full text

A method begins by a processing module determining whether a memory device of a dispersed storage (DS) unit is unavailable to produce an unavailable memory device. The method continues with the processing module determining a methodology regarding DS encoded data stored in the unavailable memory device based on one or more dispersed storage network (DSN) conditions to produce a determined methodology when the memory device is unavailable. The method continues with the processing module initiating, in accordance with the determined methodology, a rebuilding function to rebuild the DS encoded data to produce rebuilt DS encoded data when the determined methodology includes a rebuilding component. The method continues with the processing module storing the rebuilt DS encoded data within available memory of the DS unit.
