My linux partision fills up like crazy, how to counter this problem

[filo]

I see it’s solved now
I think this could be a good time to check your sudo btrfs filesystem usage /
and, if necessary, balance.
I leave you a couple of posts I bookmarked long ago to start reading how it works:

Btrfs and balance

To find out whether you need to run balance, just have a close look at the output of sudo btrfs filesystem usage /path Overall: Device size: 476.44GiB Device allocated: 252.04GiB Device unallocated: 224.40GiB Device missing: 0.00B Used: 224.00GiB Free (estimated): 250.86GiB And compare the difference between "unallocated" and "free", and "allocated" and "used". Snapshots can play a big part in this. The higher the difference, the more it i…

And how to do it (I suggest not to go for a full balance with the Garuda assistant):

Load over the CPU is too High | SLOW Response | Freezing | Hang | Crash

If this is related to BTRFS snapshots then I wonder whether a "gentle" balance (e.g. -dusage=50 -musage=50) might be a candidate for a systemd timer. Basic initial script: #!/usr/bin/bash for _mount in $(mount | grep btrfs | cut -d' ' -f3); do btrfs filesystem balance start -dusage=50 -musage=50 "$_mount" done
