Could be something wrong.

But it could also be this strangeness that df has where it can show  a
negative value, and that's OK. I've never done any research on this,
or read the code for it, but I've heard anecdotally that this happens
to give you a little bit of a safety net when it looks like your disk
is filling up.

It would be nice if someone knowledgeable could explain this.
