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 # snapper list s # | Type | Pre # | Date | User | Used Space | Cleanup | Description | Userdata -----+--------+-------+--------------------------+------+------------+---------+-----------------------+-------------- 0 | single | | | root | | | current | 1* | single | | Fri Oct 5 21:12:56 2018 | root | 1.23 MiB | | first root filesystem | 357 | pre | | Sun Apr 12 22:07:29 2020 | root | 1.88 GiB | number | zypp(zypper) | important=yes 358 | post | 357 | Sun Apr 12 22:11:09 2020 | root | 103.75 MiB | number | | important=yes 363 | pre | | Thu Apr 16 00:15:25 2020 | root | 365.25 MiB | number | zypp(zypper) | important=yes 364 | post | 363 | Thu Apr 16 00:24:28 2020 | root | 2.98 MiB | number | | important=yes 365 | pre | | Thu Apr 16 09:32:03 2020 | root | 480.00 KiB | number | zypp(zypper) | important=no 366 | post | 365 | Thu Apr 16 09:32:05 2020 | root | 608.00 KiB | number | | important=no 367 | pre | | Tue Apr 21 08:31:46 2020 | root | 480.00 KiB | number | zypp(zypper) | important=no 368 | post | 367 | Tue Apr 21 08:31:48 2020 | root | 176.00 KiB | number | | important=no 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?
