If you are using nfs version 3 on the Linux box, try these settings: filername:/vol/volpath /mntpoint nfs rw,bg,intr,rsize=32768,wsize=32768,tcp,noac,vers=3

If you are using a full-duplex network, you should not see any errors. If you are not, look at the output of ifstat and take,

# of collisions + # of errors ------------------------------ divided by the total packets and multiple by 100%. The resulting percentage should be less than 5% or you definately have network problems.

Hope this helps,

****************************************************** Sounds like RPC is working fine for you, otherwise NIS would have problems. Two thoughts, from when I've seen this in the past, for you:

1) Make sure you are using NFSv2. Linux NFSv3 is still fairly buggy.

2) Explicity define your read and write sizes. You might want to spec the retransmit as well, for now try adding the following client side mount options and see if things get better, if not tune the size alittle. Also don't use the intr option. use the options like this: mount -o rsize=8192,wsize=8192 server:/mount/point /localmount

If these don't work for you, then sorry to say, it's a networking issue. Double check your NIC settings on the Linux client to make sure you are full duplex 100, if that's what your Filer is using. Use the linux tool "mii-tool" to check. Using "mii-tool -v" you can see what the current state is, and then use the tool again to force.

If you exhast these, let me know. But one of the above should fix the problem.
