Using zones to manage capacity reduction due to storage device failure

Abstract:

A system and method for managing a reduction in capacity of a memory sub-system. An example method involving a memory sub-system: configuring the memory device with a zoned namespace comprising a plurality of zones; notifying a host system of a failure associated with a zone of the plurality of zones, wherein the failure affects stored data; receiving from the host system an indication to continue at a capacity that is reduced; recovering the stored data of the zone affected by the failure; and updating the set of memory devices to change the capacity to a reduced capacity.
