Distributed file access structure lock

摘要: A distributed file management system (DFS) with a plurality of nodes and files is disclosed. The DFS uses the UNIX operating tree structure employing inodes (data structures containing administrative information each file) to manage local surrogate (s-- inode) access existing on another node. In addition, lock (fas-- lock) multiple requests single file. primary reason for addition fas-- avoid problem deadlocks. s-- use synchronize their accesses deadlock situation where both inode await that locked by other.
