Edit: SOLVED thanks to r00ty !

Hello, I have this weird issue that my Debian 11 will tell me the root folder is full, while I can only find files for half of the accounted space.

df -h reports 56G while the disk analyser (sudo baobab) only finds 28G.

Anyone ever encountered this? I don’t have anything mounted twice… (Not sure what udev is). Also it does not add up to 100%, it should say 7.2G left not 4.1G

df -h /dev/sda* Filesystem Size Used Avail Use% Mounted on udev 16G 0 16G 0% /dev /dev/sda1 511M 22M 490M 5% /boot/efi /dev/sda2 63G 56G 4.1G 94% / /dev/sda4 852G 386G 423G 48% /home

    I think I would have expected/preferred mount to complain that you’re trying to mount to a directory that’s not empty. I feel like I’ve run into that error before, is that not a thing?

        Ahh, that might be it. I run TrueNAS too. IMO that should be the default behavior, and you should have to explicitly pass a flag if you want mount to silently mask off part of your filesystem. That seems like almost entirely a tool to shoot yourself in the foot.
