一种面向文件系统的通用故障注入工具
A General Fault Injection Tool Oriented to File System
摘要
Abstract
This paper researches the fault tolerance ability of I/O subsystem for file system error,and designs a general file system oriented software fault injection tool.The tool realizes file system fault with intercepting and modifying the file operation function jump table in kernel level,simulates a variety of temporary or permanent faults that I/O subsystem may appear.With the performance measurement tools,it compares the performance of I/O subsystem before and after file system fault injection.The results verify the fault injection tool can effectively simulate the file operation abnormal fault.关键词
