This seems to be the problem. My traceshows that VFS_CHECKEXP()
on the mount point returns EACCESS (permission denied) error.
But, the permission of the files and directories on the server are
set to -rw-r--r-- and drwxrwxr-x respectively. Even nobody should
be able to access them, I think. How should I change the
permission to make it accessable? Thanks.
