The invention provides a cluster file system, which is characterized in that: a directory server for storing catalog metadata and provide directory services; layout servers, storage layout for metadata and provide services and equipment layout; storage array for storing the content data. The invention also provides a corresponding file service method. The file service method comprises the steps: first file access client to access the directory server to retrieve the file directory information; and then access the server to obtain information distribution layout file data in the physical storage device; finally, direct access to physical storage devices to obtain data information. Compared with the prior art, the invention can further improve the extension capability of the file cluster system, and the invention has strong compatibility and small access delay.
