Context: I updated my CachyOS (Arch) BTRFS system. Some new things caused few problems especially brave browser(missing tabs), some icons missing.

So I wanted to go back to previous snapshot.

What I did: I first restored my home subvol which I saved before update. I worked.

Then I tried to restored my root partition. This is where I got the problem.

I got this error.

1001090084

I would really appreciate URGENT help

If you need any more details I can provide.

EDIT

  1. I used BTRFS Assistant to restore the root partition. And I did it while the OS is running.

( I previously did that and got no issues )

    It sounds like the error you’re seeing is from attempting to restore the root subvol (@) while the booted into the system

    To fix you’ll want to:

    1. boot from live usb (arch or cacyos).
    2. mount btrfs partition and access your snapshots.
    3. Restore root subvol from live environment

    If you are still having issues you may need to chroot into the root partition and do an update to ensure your system images match what your bootloader is expecting.
