Yes, this test is weird, I'm not sure what to do with it. If we want the writet to succeed then pynfs should first query the server for the maximum write size and use that--not every server will have 1M as the maximum. Maybe the intent was just to see if the server handles a too-large value gracefullly. But in that case it should probably use a much larger write (to ensure that it will be too much for any server), and be modified to expect the server to fail. --b.
