Metadata work, mostly - directory crawls, access checks, things like that (in CIFS). In NFS, ACCESS, READDIR, READDIR+ , stuff like that.
I think you can use 'cifs top -s ops' to see the busiest clients hitting the system. If the ones at the top have very high ops, but not many reads/writes, those could be your guys.
That said, it's all about latency. If it isn't driving latency higher, shouldn't be a concern. Those are different stats commands, though, can't remember right now......

What causes other ops? I understand that pretty much everything that hits the filer requires something but I am seeing what looks like a very high number of other ops when I do a stats show. Does this indicate a problem or is it just a busy box? It’s a mixed mode volume. Just trying to figure out what’s causing it to work so hard.
