You could try giving the nfsd processes more priority as root with rtprio. If the file /var/run/nfsd.pid exist then you could try something like: rtprio 10 -`cat /var/run/nfds.pid`. You could also try giving the other porcesses less priority like nice -n 2 rsync. But i'm am not show how this works at the other end. > The issue is more prevalent when I have >4 processes trying to read from > the nfs mounts ... should there be one mount per process? the process(es) > in question are rsync, if that helps ... they tend to be a bit more 'disk > intensive' then most processes, which is why I thought of increasing -n > ... I think you're problem is not that you disk is used havely but that you're NIC (rsync kinda does that) is. The warnings you get indicate that you're computer can't get a responce from you're server. It acts normaly as soon as it can. Why do you have rsync sync mounted nfs disks? -- Alex Articles based on solutions that I use: http://www.kruijff.org/alex/FreeBSD/ _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
