Yup, I now it's old. We have NFS server running on OpenSuse 10.3 and everything is working great. We now have a circumstance where we need detailed logging to this machine for a short period of time and the command line arguments for rpc.mountd don't seem to work as I expect them.
By appending --debug all (and optionally --foreground to run on the foreground) I was expecting to see lots of spewage and be able to monitor all NFS activity including reads, writes and deletes in realtime. But the only thing that is bring reported is when the initial mount comes from the client. All interaction with files creates no logging at all.
I thought maybe this was a syslog problem, and thus ran it in the foreground and expected to see this information displayed; yet I'm getting no logging at all.
Drop me a line in the comments area if I'm having a conceptual failure in this area. :) I also have been looking for a description of the debug levels (all, auth, call, general and parse)...yet no man pages seem to tell you exactly what they mean. I guess this might fall under 'read the source code'?
Happy weekend all.
