First, thanks for the response.....

I'm basing this on a couple of things - first when I shut down the OpenAFS
server the disk activity stops. Second, I ran iotop to examine the io usage
and the writes were going to the 2 loop devices I was using to test OpenAFS
and nothing else is using that area but OpenAFS. And finally, top shows
fileserver popping up every 10 seconds when the disk activity to the loop
devices is occurring and then it goes back to sleep.

Is it possible that because I'm using loop devices something out of the norm
is occuring?

John
