Abstract:

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 i  mplemented and tested on the HANDY （High Availability aNd Dynamic scalabilitY） file system, which is designed and developed by ourselves. The test ressults are satisfactory and reach the design goal of the HANDY cluster file system,

Key words: （metadata, parallel file system, high availability;dynamic scalability）
