A study of the fault-tolerant PVFS2

A distributed file system (DFS) is any file system that allows access to files from multiple hosts via a shared computer network. Such a system allows multiple users on multiple machines to share files and storage resources. Increasing reliability and usability is a critical issue for distributed file systems. In this paper, we need to thoroughly analyze the architecture of the Parallel Virtual File System (PVFS), and further propose the possibility of enhancing the fault-tolerance and reliability of PVFS.
