Distributed file system is an essential part of data intensive works as it is used as a primary storage solution. Distributed file system also provides distributed environment of processing for fast and effective processing of large set of data. Over the years, there are a number of DFS has been developed. All the DFS are designed to handle a large set of data efficiently, so that users can access the data quickly regardless of how the data are stored. For a user it becomes hard to choose one against a number of available DFSs. A thorough study about the DFSs will definitely guide users to choose their favorable DFS in their applications. In this paper, we give a brief description about GFS, HDFS and GlusterFS and then compare them on some fundamental issues of DFS such as scalability, transparency and fault tolerant.
