After a recent update my whole computer is moving very slowly, When I boot up I get a message left that I have around 10mb left of data? although I have 300gb left of storage. I see my parition has boot set at 1gb is that normal? Any idea of how I can fix this my whole pc is lagging badly, and takes 2-3 minutes to boot up, I have a 2070 super and everything use to run smoothly.
Possibly too many retained kernels.
Can you check the output of cat /etc/dnf/dnf.conf, and that of ls -lh /boot, and post them back as preformatted text (</>)?

Your boot partition is nearly full.
There are two options:
- increase boot partition by resizing your Btrfs partition (make sure you have working backups)
- delete some of the eight kernels that you have installed.
What are these cband cbrt kernels?

That’s strange. Did you upgrade from F39?
You can delete your old kernels, and keep the last 3 ones.
@augenauf , any idea why the latest kernels are both for F39 and F40 there?

Yes I did just update from Fedora 39.
No idea.
weird, first didn’t notice that. strange mix of kernels. I guess we wait to learn what cb kernels are and how they were installed.
I suggest we take a look at uname -a and let OP perform sudo dnf distro-sync after having cleared at least one kernel (it may otherwise fail due to insufficient space)
The please show us the output of sudo dnf repolist and uname -a.
Did you not manually install some third party kernel builds?
@rester , I have to leave my desk for a couple of hours, but it seems to be leaving you in good hands.

I found bieszczaders/kernel-cachyos Copr. does this ring a bell @rester ?
Should only have 3. . .
does that not only apply for “official” kernels from Fedora repo? If OP installed some third-party kernel from copr, not sure the 3 applies.

That’s where the cb kernels are coming from.
You need to make some space on /boot by removing kernels and then run sudo dnf distro-sync

I appreciate all the help, I just removed all of the COPR’s most I did not use or need. Now to remove the kernel’s what would be the command.
sudo rm config-6.6.2-cbrt2.0.fc39.x86_64
rm: cannot remove 'config-6.6.2-cbrt2.0.fc39.x86_64': No such file or directory
And I’d be safe removing all of them except the ones that are FC40 for Fedora 40.
I ended up clearing like 500mb of data from the 1.1gb. Now I just have to remove those kernels from the ls -lh /boot command, It keeps saying " No match for arguement"
Try sudo dnf remove kernel-core-kernelNumber*,
where kernelNumber is the number of the kernel to be removed, e.g. 6.9.4-cb4.0.fc39.
