The explosive growth of the Web contents has led to increasing attention on scalability and availability of file system. Hence, the ways to improve the reliability and availability of system, to achieve the expected reduction in operational expenses and to reduce the operations of management of system have become essential issues. A basic technique for improving reliability of a file system is to mask the effects of failures through replication. Consistency control protocols are implemented to ensure the consistency among replicas. In this paper, we leveraged the concept of intermediate file handle to cover the heterogeneity of file system and proposed an efficient data consistency control scheme supporting dependence checking among writes and management of out-of-ordered requests for file server group. Finally, the results of experiments proved the efficiency of the proposed consistency control mechanism. Above all, easy to implement is our main design consideration.
