摘要: 在分析导致I/O节点失效主要原因的基础上, 提出一种有效的并行文件系统容错方法: 子文件循环冗余备份. 该方法保证了I/O节点失效时并行文件的正常访问, 提高了并行文件系统的可靠性和有效性.

关键词: 并行文件系统, 容错, 可靠性, 有效性, 节点失效

Abstract: Based on the analysis of I/O node failure, an efficient fault tolerance method called Round robin Redundant Backup of Subfile is propo sed. This method ensures that the parallel file can be accessed when the I/O node is failure. Through this method, the reliability and availability of a parallel file system are improved.

Key words: parallel file system, fault tolerance, reliability, a vailability, node failure
