I noticed the "Stale file > handle when mounting nfs" message but I don't get the "stale file > handle" messages from mount, probably as I'm not running any linux clients. These kinds of problems are usually related to your net interface device driver or the TCP stack.
A couple of things to try: - Disable TSO (look for a sysctl with "tso" in it). - Try using mount options rsize=32768,waize=32768 to reduce the I/O size. Some device drivers don't handle long chains of mbufs well, especially when the size is near 64K. (These issues have been fixed in current, but if a bug slips into a net driver update or ???) - Look at recent changes to the net device driver you are using and try reverting those changes if you can do so. - Capture packets and look at them in wireshark (which knows NFS) and see what is going on the wire. There hasn't been any recent changes to NFS that should affect NFSv3 mounts or to the kernel rpc, so I doubt the NFSv4.1 changes would be involved. rick _______________________________________________ freebsd-current@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
