Fixing Full / Root Partition on Fedora

If your root (/) partition is nearly full but /home has plenty of space, follow these steps to clean up and free disk space.

📊 Quick Stats Example

$ df -h /
Filesystem               Size  Used Avail Use% Mounted on
/dev/mapper/fedora-root   49G   46G  682M  99%

✅ Step-by-Step Cleanup

1. Check What’s Taking Space

sudo du -ahx / | sort -rh | head -n 30

This shows the top 30 space consumers on the root filesystem, excluding mounted ones like /home.

2. Clean DNF/YUM Cache

sudo dnf clean all

3. Remove Old Kernel Versions

List installed kernels:

rpm -q kernel

Remove older versions (keep the latest 2):

sudo dnf remove kernel-<version>

4. Vacuum Journal Logs

Check journal size:

sudo journalctl --disk-usage

Reduce journal size:

sudo journalctl --vacuum-size=500M

5. Remove ABRT Crash Dumps

sudo rm -rf /var/spool/abrt/*

These are crash reports, safe to delete if you don’t need diagnostics.

6. Flatpak Cleanup - Optional

If NOT using Flatpak apps:

sudo flatpak uninstall --unused
sudo rm -rf /var/lib/flatpak

7. Podman and Docker Cleanup

To remove all unused Docker data:

docker system prune -a
# or
podman system prune -a

⚠️ Make sure you don’t need the old images/containers.
