Kaisen just installed and with 45% of disk used :(

Hello to all of you!

I have just installed Kaisen. I love it!

Now; it’s impossible that a newly installed system already has out of 221 GB, 121 GB free (45,2% occupied)

Well I do not understand what happens {this, maybe because I used upgrade and not kaisen update ?

Which I must have duplicate packages or more than that, I don’t know.

Thanks for your help.

Hello and welcome @judd,

Can you send me the result of the command sudo apt-btrfs-snapshot list?

It’s possible due to snapshots automatically taken when an update or packages are installed.

Of course!

$  sudo apt-btrfs-snapshot list
[sudo] contraseña para judd: 
Available snapshots:

Oh whoua. There were a lot of them in 4 hours.

Would you like delete all snapshots taken?


It cost me a lot to install it and in the end I did it, by the way the installations with netinstall didn’t work, almost at the end I was getting kernel-panic…
Also, it would not let me select a file system other than Btrfs.

I would like to solve this problem with the snapshots.

Kaisen isn’t installed?

If only… I think so

 $ uname -a
Linux kaisenlinux 5.17.0-kaisen1-amd64 #1 SMP PREEMPT Kaisen 5.17.3-1kaisen (2022-04-23) x86_64 GNU/Linux


I apologise for the delay in replying, but I speak Spanish and not English. I have to translate and then paste to reply, thank you!

The kernel version currently used isn’t an indicator to check if the system is installed.

But I think that your system is installed, elif the command apt-btrfs-snapshot list wouldn’t have worked.

The installer define BTRFS as default filesystem. But it’s possible to select an other filesystem if you would you like use an other.

The snapshots will not resolves problems due to the installation, snapshots only restores the system before the installation of packages.

Simply the df -h or lsblk commands can be an indicator.

With my explanations, in relation to your initial question, to resolve your problem, you need to delete many or all snapshots to reduce the disk space currently used.

Would you like delete all snapshots?

Thank you!

I have the answer to my question with that :grin:

Sure, I have no problems, it breaks, it reinstalls, no problems from my side :+1:

Okay, you have just run this command: sudo apt-btrfs-snapshot delete-older-than 0d

After that, the space disk used will be reduce.

Also I have the cpu at more than 100%, I always fix it with pcie_aspm=off and pci=nomsi,noaer in /etc/default/grub
But this was not the case…

Mmmm no ↓


Reboot ??

Your CPU isn’t used at more 100%.

It’s normal that each CPU core either a little used.
