Discrepency between du and df on an empty filesystem. I suspect that it is the meta-data files. There are invisible files that hold information about the filesystem.
New information: I bumped up the maxfiles on all four filers to 2.5 million inodes. The adm1-na1 and adm1-na4 both printed the warning about having more than twice as many files as needed, but adm1-na2 and adm1-na3 did not. However, after all four were set to 2.5 million files, the df did not change (trying after umounting and remounting the filesystems, rebooting the filers, etc.).
As I said previously, maxfiles on the filers should have been identical, assuming that previous maxfiles settings are lost when the filesystem is wiped clean and recreated. I'm going to wipe everything out again after the latest rounds of tests, and I'll try to reproduce this condition.
