Storage unit (SU) operative to service urgent read requests

Abstract:

A computing device includes an interface configured to interface and communicate with a dispersed storage network (DSN), a memory that stores operational instructions, and processing circuitry operably coupled to the interface and to the memory. The processing circuitry is configured to execute the operational instructions to perform various operations and functions. The computing device determine status of a set of memory devices of one or more sets of storage units (SUs) that distributedly store a set of encoded data slices (EDSs) within the DSN. The computing device detects one or more memory devices thereof that are failing and determines a number of available EDSs. When an insufficient number of EDSs are available, the computing device issues urgent read slice request(s) to recover additional available EDS(s) and facilitate temporary storage thereof within the DSN.
