Abstract
A file server apparatus includes a second file system volume including cache data of a first file system volume stored in a shared file storage apparatus. The file server apparatus determines the operation type indicated by an access request to the first file system volume from a client. When the operation type is directory operation, the file server sends an instruction of directory operation to the shared file storage apparatus, and then transmits a completion response to the client. When the operation type is file operation, the file server apparatus executes a file operation in the second file system volume, transmits a completion response to the client, and then transmits a file operation instruction to the shared file storage apparatus.
