Following up my own post: my kludge was
ls -Rli | sort -u | awk '{total += $6;}END { print "total: " total;}'
My result was pretty much what df gave, so we do have a problem. Now I'm looking into alternatives, like incremental tar backups....

What I need to figure out, so that we don't blow out the filesystem, is how much space is *really* in use. I'd like something a bit faster and more elegant than, say, ls -Ri | awk '{print $!;}' > filelist, and then a shell script to loop
