It seems to work OK, but I am not exactly pushing it, and I have not rigorously tested the failover (I am only using it for a couple of test scratch areas at the moment). It was very easy to setup (except that since we do not run the DNS here at AZ, we couldn’t get a round robin DNS entry setup, so we have to explicitly point clients at one of the servers). <o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>When I asked a couple of questions about CNFS at the GPFS users meeting at Daresbury earlier this year, there were people who were using it, but it seemed to me that the general consensus was that people preferred using CTDB to get highly-available NFS and CIFS serving.
