NFS V2

• design goal: stateless protocol

  • simple servers,
  • works well on unreliable networks & computers

• client simply retries until it receives a reply

  • connectionless UDP ok

• requires operations to be stateless and idempotent

• alas, many file(system) operations aren't

  • -> additional protocols, not part of core NFS
  • -> operations history kept on server/client ?
