    • The present invention relates to a method and an apparatus for providing a virtualized file system enabling indirect access to a second file system in a data storage system comprising a plurality of client computers 100 and a second file system managing unit 410 for managing the second file system and enabling client access to the second file system, the method comprising interconnecting a first file system managing unit 310 between the plurality of client computers 100 and the second file system managing unit 410, creating a first directory /root in a first file system managed by the first file system managing unit 310, associating a first directory /root of the second file system with the first directory /root of the first file system, enabling on-demand virtualization of the second file system by the first file system managing unit 310 based on client requests received from the client computers 100 at the first file system managing unit 310 and based on the association between the first directory of the first file system and the first directory of the second file system, and enabling indirect client access to the second file system through the first file system.
    • 本发明涉及一种用于提供虚拟化文件系统的方法和装置,该虚拟文件系统能够间接访问包括多个客户计算机100的数据存储系统中的第二文件系统,以及用于管理第二文件系统的第二文件系统管理单元410 并且使客户端能够访问第二文件系统,该方法包括在多个客户端计算机100与第二文件系统管理单元410之间互连第一文件系统管理单元310,在由第一文件系统管理单元310管理的第一文件系统中创建第一目录/根 第一文件系统管理单元310将第二文件系统的第一目录/根与第一文件系统的第一目录/根相关联,由第一文件系统管理单元310基于对第二文件系统进行按需虚拟化 根据在第一文件系统管理单元310处从客户端计算机100接收的客户机请求,并且基于f之间的关联 第一文件系统的第一目录和第二文件系统的第一目录,并且允许间接客户端通过第一文件系统访问第二文件系统。
