I have a AMD64 FreeBSD 8.0 server with ZFS filesystem being shared via NFS. These are being accessed by the clients. The clients are a mix of FreeBSD 6.2 32bit and FreeBSD 7.0 64bit. I have seen similar behavior from both versions of FreeBSD as clients. The behavior that I'm seeing is that everything is fine for a period of time and then the client starts "writing" large amounts of data to the NFS server. "Writing" is in quotes as nothing is actually being written to disk - this can go on for 12+ hrs or more - until the client is rebooted. It appears to cap out at around the 10-20Mbps rate and just sit there. Other clients are fine during this time. Client mounts in /etc/fstab look like: 192.168.1.33:/tank/share /usr/local/www/share nfs rw,-b,-i,-U,-3 0 0
One other thing you could try is switching to TCP mounts (replace -U with -T). There are a couple of others that have reported NFS server problems (all different symptoms) where the problem went away when they switched to TCP. rick _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[email protected]"
