Q: Best NFS mount options from Linux to Xsan?

So we are adding Linux clients to our network and I'm looking to learn the best NFS mount options to put in the fstab file. Right now they are set "defaults 0 0" and we are having problems. I assume because they are hard mounting. This is from the /proc/mounts file for one of the clients connecting to the Xsan:

10.X.X.X:/snet /snet nfs rw,relatime,vers=3,rsize=65536,wsize=65536,namlen=255,hard,proto=tcp,timeo=600, retrans=2,sec=sys,mountaddr=10.X.X.X,mountvers=3,mountport=706,mountproto=udp,ad dr=10.X.X.X 0 0

Xsan 2.2, 2 MDCs running 10.6.4, Promise Array.

Mac OS X (10.6.4)

    What Linux distro are you using?

    I've used this successfully with a few different distros:

    192.168.x.x:/Volumes/XSAN /media/XSAN nfs defaults 0 0

    We are using many, Red Hat (RHEL 5.4), Fedora and some Ubuntu.

    So you just use a default mount and didn't have any problems? This does work for us, but it seems to break every now and then, so I am wondering, is a default, hard mount is the right way to go?

    I have had no problems. Using Xsan reshare for a Linux render farm. And image sequence playback station. What problems did you have? You said it would break. How?

    So we have finally solved this. It turns out that the defaults work just fine. Our issues were solved by changing which MDC was hosting the export, dividing up the workload a bit, our primary was running out of RAM.

    Secondly, I added intr and soft to the NFS options, the smoothed things out further.
