I think the reason it is saying 100% is that Linux reserves some space
on each drive in case the system needs some, in order to prevent the
OS from crashing horribly.
It may be /tmp that is being written to.
I like ncdu for finding where space is being used up.  Install it if
necessary and run
sudo ncdu /
It will show you usage on a folder basis and you can step in to look
at lower levels. You need sudo if running on / otherwise it errors on
dirs it cannot read.
