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.
Claims20
A system comprising:
- a memory device;
- and
- a processing device, operatively coupled with the memory device, to perform operations comprising:
- 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.
A method comprising:
- 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, by a processing device, 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, by the processing device, the set of memory devices to change the capacity to a reduced capacity.
A non-transitory computer-readable medium storing instructions, which when executed by a processing device, cause the processing device to perform operations comprising:
- configuring a set of memory devices with a zoned namespace comprising a first zone and a second zone;
- notifying a host system of a plurality of failures associated with the plurality of zones, wherein a first failure affects stored data of the first zone and a second failure affects stored data of the second zone;
- receiving from the host system an indication to continue at a capacity that is reduced after each of the plurality of failures;
- recovering the stored data of the first zone that was affected by the failure;
- and
- updating the set of memory devices to change the capacity to a reduced capacity after each of the plurality of failures.
