(The NFS server's IP address moves from one machine to the other.) 3) Access the mounted NFS share. Expected results: Accessing the NFS mount works fine immediately. Actual results: Accessing the NFS mount hangs for 15 minutes. Then the TCP connection times out, a new connection is established, and it works fine again. After the IP moves, the new server responds to the client with TCP RST packets, just as I would expect. I would expect the client to tear down its TCP connection immediately and re-establish a new one. But it doesn't. Am I confused, or is this a bug? For the duration of this test, ufw was disabled on the client machine. I have a packet capture. We've been using UDP instead of TCP as a work-around. The system is running Ubuntu 14.04 with Linux 3.13.0-76-generic.
