Prepare for these questions before you come to the Lecture.

NFS:

Q1: What RPCs would be generated from the following sequence of code?

    fd = open("file.txt", 0);
	 read(fd, buf, 8192);
    close(fd);

Q2: What's the point of the generation number included in a file handle?

Q3: NFSv3 supports asynchronous writes (i.e. server acknowledges WRITE request before it writes

   using our pop quiz knowledge.

NFS Toolkit:

Q1: What is the deadlock situation with userlevel file servers?
