Thank you Radek Sorry - I don't think there's an easy answer to this but someone who knows more about nfsd may be along soon. However, if no better idea turns up you could try using dtrace to monitor the underlying calls (or hack nfsd?). I have thought about doing this myself, but it is only available in new FreeBSD releases and the DTrace user guide (from Sun) is 60 pages long and gives me a headache. I know Linux people do something similar using SystemTap. Is the attribute caching on the client set correctly? Or even working (bug?) BTW, what you're seeing isn't unusual.

You can't get tcpdump to print it, but the getattr reply does include the inode of the file. If you start up wireshark and capture the same packets (or open a capture file created by tcpdump), the inode is stored in the nfs-obj_attributes-attributes-fileid field. You can then use find / -inum 12345 to locate that inode on disk. -- Dan Nelson dnel...@allantgroup.com ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
