Is df really df or an alias to 'df -t nonfs'? Yes, it really is the untruncated output of "df -h". I also tried the "df -t nonfs" and it gives exactly the same output as "df". What are you expecting that is not present in the output ? > Is it possible that nfs directory got written to /usr at some point in time? > You would only notice this with du if the nfs directory is unmounted. > Unmount it and ls -al /usr/mountpoint should only give you an empty dir Bingo!! That is exactly the problem. An NFS mount was hiding a 17G local dir which had an old copy of the entire NFS mounted dir. I guess it must have been written incorrectly to this standby server by RSYNC before the NFS mount was put in place. I will add an exclusion to rsync to make sure it does not happen again even if the NFS dir is not mounted. Thank you for your help, you have saved me much time rebuilding this server.
