A long time ago I asked this OpenSuSE/Linux question: How can a partition be full if du does not show it is? – Linux on Super User.
With help of the OpenSuSE forums, I did figure out the source of the problem and solution, but I totally forgot to blog about it.
So below it is, just in case SuperUser ever shuts down, or the StackOverflow moderators are taking over SuperUser as well.
But first the comments in the questions about where I found the source and solution:
I found it through the openSUSE forums: it uses btrfs and snapshots. So the snapshots take up a lot of space. And I need to find out a way to delete old snapshots. forums.opensuse.org/english/get-technical-help-here/…
and
I think I found it: nrtm.org/index.php/2012/03/13/…
I wasn’t alone, so here are some more useful links and links from people asking for help:
