du shows file sizes
df shows filesystem sizes.
if you did a du -sk* that would list out all the files and their sizes in that directory.

why du and df has differenct output?
usually people explain:
This is more than likely what you are seeing here and is nothing to be concerned about.
As you know free space on Oracle file systems can be measured by what space is
left within the existing table space since Oracle grabs the space and maintains free space within it.
we did a Oracle database shut down.
but same result.
Thanks a lot in advance

du shows file sizes

The difference is : du check directory/file size (if you run 'du -sk*' it will list out all the files in the dir and their sizes)
df checks filesystem size... which would explain why df is larger.
