Use 'du -xh --max-depth=1 /' it will clean up your output and show you only things on the root partition.
Note the reason for -x . -x is equivalent to --one-file-system . It says that when searching from a directory, include only descendants in the same filesystem.
Though rather unlikely, it is possible that none of /* are in the same filesystem as / , hence the need for / rather than /* .
