My Fedora 90GB root partition suddenly ran out of space?

[iamdumdum1234 (Dumdum TheDum)]

Hi everyone,

Originally I got a 90GB partition to put Fedora Linux on, thinking that all that space won’t fill up for at least a while.

Now, around a month later, it seems to have suddenly fill up, and now I only have 1.8GB left.

However, when looking inside, it seems like the Disk Usage Analyzer can only detect 22.7GB used.

I know it says “File may take more space then shown”, but IMO, I don’t think those files could expand by that much.

As I can see in the directories, it’s mostly my Waydroid, Flatpak and Wine storage taking up space.

I used to have some virtual machines in GNOME Boxes that I deleted before, then switched to virt-manager because it used my Intel graphics instead. I just deleted my Ubuntu 25.10 VM because of this, and even THAT did not give me some space back!

Can anyone help me with this? Thank you all.

Is it possible that btrfs snapshots are consuming the “missing” space?

You could install the btrfs-assistant package to take a look at this.

Root is full, can't determine why

This is great, thank you. It is indeed user error, and the extra volume usage is the timeshifts. I am baffled as to why it is not showing up in the size for run, or in dolphin. I guess I still have windows intuition in some ways. This enabled me to pin down exactly what I’d done; I initially moved the location for the timeshifts off root, so timeshift was telling me there wasn’t any files there, and they are hidden (to me) via the other methods I was trying to find the volume. I changed the loc…

This was the solution! I used BTRFS Assistant to create daily snapshots without seeing how things really worked, so I didn’t know it was one of the backup partitions that took up space. Was it because I used timeshift before?? Problem solved, thank you so much!
