subfile

After that, each node propagates its subfile to the other k-1 nodes in the group.

之后，每个节点传输它的子文件其他的k-1个节点。

Based on the analysis of I/O node failure, an efficient fault tolerance method called Round-robin Redundant Backup of Subfile is proposed.

摘要在分析导致I/O节点失效主要原因的基础，提出一种有效的并行文件系统容错方法：子文件循环冗余。
