摘要： 随着存储数据的爆炸性增长和集群技术的快速发展，集群文件系统的研究越来越成为一个焦点，该文设计并实现了一个多级集群文件系统（MCFS）的全局命名空间，MCFS系统采用元数据分层管理思想，建立一个统一的元数据树，从而使整个系统运行在一个松耦合、异构的环境下实现全局命名空间，提高了系统的并行性和可扩展性。在介绍了MCFS命名空间管理的同时，进行了相应的试验测试和性能分析。

Abstract: With the quick development of storage and cluster technology, the cluster file system research becomes a more and more important issue. This paper presents the design and implements the global name space in the multilevel cluster file system(MCFS). It brings forward a metadata multilevel policy, thus forms a uniform metadata tree, so multilevel file cluster system can implement the global name space in a loose coupling, isomerous circumstances, improving the system’s parallelism and scalability. After introducing the global name space in the multilevel cluster file system, some experiments is made to analyze the performance and scalability.
