WebNVMe Fault Injection ===== Linux's fault injection framework provides a systematic way to support error injection via debugfs in the /sys/kernel/debug directory. When enabled, the default NVME_SC_INVALID_OPCODE with no retry will be injected into the nvme_end_request.

WebThe ability to drive NVMe targets with a wide range of configurable attributes provides engineers with a flexible, scalable tool to simulate real disk and memory access environments and issues. Development, qualification and certification test cycles can be highly automated, reducing time and surfacing issues and errors. ez hemlock\u0027sWebIf the scope of the fault injection capability is limited to a single kernel module, it is better to provide module parameters to configure the fault attributes. add a hook to insert failures.
