Are there problems with any other commands like mount, lsof or du? Do
the contents of /etc/mtab match what mount is showing as mounted?

Is there anything in /var/log/messages ? Does "strace df -h" give any
indication where the problem lies? Are you sure it's /bin/df you're
running? Does the binary have the same size and md5sum as a working df
on another machine with the same version of the coreutils package?
