Freeing space on Ubuntu does not work [duplicate]

The df command tells me I have no free space left on the root drive

but I deleted a lot of files on the root and still this does not freeing up space.
This is the result without the home folder, because home is not mounted on root

the 19GB from the df command is not the same as the 9,8GB from the du command?

I deleted all the data with “rm” commands so I guess the data is really gone and not caching up somewhere…

Does any body know what’s going on here, and how I can free some space?

Answer

Are the files still open?
That would explain the space not being reclaimed.

You may want to use lsof to check which process has your unlinked files open.
