At this point I'm unsure where to go next. How do I free up my disk space?

just in case this lack of room is preventing correct working, you may know that with btrfs you can make room by adding an other partition, may be even on an other disk, including usb3 disk (to be removed after cleaning)

Thanks for the information. I'm not at that point yet, there are still ~3GB free. Robert -- To unsubscribe, e-mail: opensuse-support+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-support+owner@opensuse.org

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.

# df -h / Filesystem Size Used Avail Use% Mounted on /dev/nvme0n1p1 120G 116G 3.8G 97% /

btrfs seems to agree - the disk is full

# btrfs fi df / Data, single: total=117.47GiB, used=113.72GiB System, single: total=32.00MiB, used=16.00KiB Metadata, single: total=2.50GiB, used=1.22GiB GlobalReserve, single: total=173.62MiB, used=0.00B

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

Ouch, so not btrfs at all. FWIW, I had a 76 G file at /tmp/dumps/robert_stdout.txt, caused by https://github.com/ValveSoftware/steam-for-linux/issues/6901 I removed it and all is well now.
