Managing storage device errors during processing of inflight input/output requests

An article of manufacture comprising a non-transitory processor-readable storage medium having stored therein program code of one or more software programs, wherein the program code is executable by one or more processors to implement a method comprising:

• managing, by a storage control system, a plurality of storage devices of a storage node;
• instantiating, by the storage control system, one or more logical storage devices, wherein each logical storage device is associated with a respective storage device of the plurality of storage devices, and wherein the one or more logical storage devices are maintained by the storage control system in a non-volatile memory device of system memory of the storage node;
• receiving, by the storage control system, an input/output (I/O) write request comprising data to be written to at least one storage device of the plurality of storage devices managed by the storage control system;
• commencing, by the storage control system, a write operation to write the data to the at least one storage device;
• and
• in response to a storage device I/O error resulting from a failure of the write operation associated with the at least one storage device, the storage control system:
• accessing a logical storage device in the non-volatile memory device of the system memory, which is associated with the at least one storage device for which the storage device I/O error was returned;
• and
• writing the data to the accessed logical storage device in the non-volatile memory device to complete the failed write operation.

An apparatus, comprising:

• at least one processor;
• and
• a system memory configured to store program code, wherein the program code is executable by the at least one processor to implement a storage control system which is configured to:
• manage a plurality of storage devices of a storage node;
• instantiate one or more logical storage devices, wherein each logical storage device is associated with a respective storage device of the plurality of storage devices, and wherein the one or more logical storage devices are maintained by the storage control system in a non-volatile memory device of system memory of the storage node;
• receive an input/output (I/O) write request comprising data to be written to at least one storage device of the plurality of storage devices managed by the storage control system;
• commence a write operation to write the data to the at least one storage device;
• and
• in response to a storage device I/O error resulting from a failure of the write operation associated with the at least one storage device, the storage control system is configured to:
• access a logical storage device in the non-volatile memory device of the system memory, which is associated with the at least one storage device for which the storage device I/O error was returned;
• and
• write the data to the accessed logical storage device in the non-volatile memory device to complete the failed write operation.
