Cloud storage is the development direction of data storage now-a-days, and MooseFS provides a good solution for cloud storage. But as a kind of typical distributed file system, the problem of load balancing among chunk servers affects the use of MooseFS. Though MooseFS has provided certain load balancing capability, but it takes into account only the consumed space, and which causes the chunk servers with larger space were overburdened. In this paper, the authors analyzed the load balancing algorithm among chunk servers in MooseFS, and proposed an improved load balancing algorithm.
