Special Status Code Explanation

Erasure Coding Subsystem

Each module of the erasure coding subsystem supports audit logs. If audit logs and monitoring metrics are enabled (you can refer to the documentation), you can view the service request status code information in the audit log file or the monitoring metric service_response_code. The following describes the special status codes of each module.
