Hi,
I was notified today that space on my / partition is running out. I have set aside 120GB for it, and now it's basically gone.

btrfs seems to agree - the disk is full

Snapper was my first option, so tried to check that

I run docker and I know that it uses btrfs as well so I tried to clean any dangling objects
# docker system prune -f Total reclaimed space: 0B
I tried to analyse the used disk space with $ xdg-su -c 'baobab'
But it only discovered 19.3 GB of used space. I'm intereted in where the other ~90 GB have gone.

Note that snapper was a bit confused about how the snapshot sizes, as setup-quota failed
# snapper setup-quota Quota error (qgroup already set).
but no used space information was present in the output, so I manually enabled the quota with
# btrfs quota enable
Still, I get an error message when running cleanup
# snapper cleanup number quota not working (preparing quota failed)
although the cleanup seems to be running.
At this point I'm unsure where to go next. How do I free up my disk space?
Thanks, Robert
