摘要
本文研究集群文件系统的特征,提出了一种分布式元数据管理技术。该技术通过哈希方式分布元数据对象、自侦测自适应和连续相邻节点备份的方法,实现了元数据的动态扩展和高可用。在我们研制的HANDY文件系统中采用了这项技术。测试结果说明,HANDY的元数据扩展性是令人满意的,实现了动态可扩展和高可用的设计目标。
This paper studies the characteristics on the cluster file systems, and proposes a solution to the management of distributed metadata. The solution has achieved the goals of high availability and dynamic sealability by means of the Self- Detect-Self-Adopt and Neighboring Node Backup. And it had been implemented and tested on the HANDY （High Availability aNd Dynamic scalabilitY） file system, which is designed and developed by ourselves. The test results are satisfactory and reach the design goal of the HANDY cluster file system,
