Prioritizing memory devices to replace based on namespace health

摘要

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 detects memory error(s) associated with a plurality of sets of memory devices of sets of storage unit(s) (SU(s)) within the DSN that distributedly store a set of encoded data slices (EDSs). The computing device facilitates detection of EDS error(s) associated with the memory error(s). For a set of memory devices, the computing device establishes a corresponding memory replacement priority level and facilitates replacement of corresponding memory device(s) associated with the EDS error(s) based on the corresponding memory replacement priority level.
