Formalizing Google File System

Google File System (GFS) is a distributed file system developed by Google for massive data-intensive applications which is widely used in industries nowadays. In this paper, we present a formal model of Google File System in terms of Communicating Sequential Processes (CSP#), which precisely describes the underlying read/write behaviours of GFS. Based on the achieved model some properties like deadlock-free, and consistency model of GFS can be analyzed and verified in the further work.
