I think that was one of the suggestions (I've Googled a lot, tried different things, etc.) when looking at tuning NFS and such. I have now mounted it as such: raid01:/home on /local/home type nfs (rw,nodev,_netdev,noatime,nfsvers=3,tcp,rsize=16384,wsize=16384,hard,intr,nolock,timeo=600,addr=192.168.1.151) I still consistently and easily get the [root@web03 ~]# dmesg -c nfs: server raid01 not responding, still trying nfs: server raid01 OK nfs: server raid01 not responding, still trying nfs: server raid01 OK After only a minute or two of nhfsstone (with default parameters) Any other suggestions? Increasing/decreasing wsize/rsize? Changing hard to soft? I'm willing to try anything.
