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 )

  1. I pressed crtl+d and got 👇🏽

    First of all thanks.

    1. I booted live Mint.

    2. Mounted btrfs partition.

    3. I renamed the backup (snapshot that btrfs assistant created while originally restoring before) to @.

    Now my system boots but .snapshots are in original @ (which now I renamed as something else). I want those snapshots or delete altogether (for freeing up space).

    1. I tried to rsync old snaps to new @. It worked, but now I have delete the snaps from old @ (source of snaps). Which I cannot do for some reason. It says read only file system. I typed sudo btrfs property set -ts /path/to/snapshot ro false it retuned error cannot retrieve properties

    2. Then I tried to delete .snapshots subvolume altogether, but it says directory not empty.

    I used sudo btrfs subvolume delete /path/to/.snapshots

    (.snapshots is a separate subvol mounted on old @ subvol)

    Now I have a working system but all my old snaps are stuck on old root. Which I cannot delete.

    Idk what to do.😵‍💫
