Problem
1. In NFS, when a file is opened, a file handle is returned, analogous to a file descriptor being returned in UNIX. Suppose that an NFS server crashes after a file handle has been given to a user. When the server reboots, will the file handle still be valid? If so, how does it work? If not, does this violate the principle of statelessness?
2. In the bit-map scheme of is it necessary that all machines caching a given file use the same table entry for it? If so, how can this be arranged?
