Abstract:
A method begins with determining a memory device of a dispersed storage network (DSN) has an issue, where a data segment of a data object is dispersed storage error encoded to produce a set of encoded data slices that is stored in a set of storage units of the DSN, where a storage unit includes a plurality of memory devices that includes the memory device, and where the memory device stores an encoded data slice of the set of encoded data slices. The method continues by identifying an issue with the memory device and by identifying sets of encoded data slices. The method continues by generating an additional encoded data slice for each of the sets of encoded data slices to produce a group of encoded data slices and storing the group of encoded data slices in at least one other memory device of the DSN.
