Abstract
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 detecting a failure (partial or full) of a dispersed storage (DS) unit memory device within the DSN. The method continues by tracking namespace ranges of encoded data slices intended for access in the failed DS unit memory device. The method continues by redirecting access of the encoded data slices reflected by the namespace ranges from the failed DS unit memory device to a failover DS unit memory device.
