Why is my Fedora server’s SSD showing as full when I think there’s space left?

The reason for the discrepancy in numbers is likely due to how storage space is measured. Your web console might be using decimal (base 10) for measuring storage, whereas `df -h` uses binary (base 2) where 1 GB equals 1024^3 bytes. That could explain the differences you're seeing. As for why it says it’s 100% full despite you thinking there's space left, it's because of reserved space for the root user. Filesystems like ext4 typically reserve about 5% of the total space for root, meaning that `df` doesn't count those as available even if they aren’t being used. You can tweak this with the `tune2fs` command if needed.

Also, just a heads up, since this is a 1 TB drive and your `df` output is showing 870 GB used, you might want to investigate what is really using all that space. Sometimes, hidden files or logs can add up quickly. If your root is on a separate drive, you shouldn't normally have reserved space issues affecting this SSD.

You're dealing with a full drive beyond just the kernel files; at this rate, even getting a simple directory created isn’t feasible. It sounds like you should check out the `du` command to find out which files are taking up the most space. A good starting point would be checking log files in `/var/log`. Often, those `.log` files can be safely deleted or rotated to clear up some space.
