However, thats made me think that I should have something other than the defaults in the client fstab - any suggestions for tuning NFS for large video files? I'm running Gentoo at both ends and I'm getting the error "nfs warning: mount version older than kernel" but its running version 3 OK according to /proc/mounts so what is the version difference its complaining about?
