Discuss the advantages and dis

The advantage is that the application can deal with the failure condition in a more intelligent manner if it realizes that it incurred an error while accessing a file stored in a remote filesystem. For instance, a file open operation could simply fail instead of hanging when accessing a remote file on a failed server and the application could deal with the failure in the best possible manner; if the operation were to simply hang, then the entire application hangs which is not desirable. The disadvantage however is the lack of uniformity in failure semantics and the resulting complexity in application code.
