My USB disk wich hold garuda wayfire has turned read-only because of a btrfs problem.
Here is a copy of the pertinent part of the system journal :

After booting from the laptop disk on my other linux (opensuse tumbleweed), I haved tried a "btrfsck" and it abended with the following message :
I had many blocks with the following message
type WARNING: tree block [17807228928, 17807245312) crosses 64K page boudnary, may cause problem for 64K page system
then the rest goes :

or paste code here
The last dump from the btrfsck is similar from the first dump showed in this post.
What should I do with that ??? I'm really puzzle. I have all the data on my laptop disk. The USB disk is more a backup disk with Garuda wayfire installed and a large subvolume for backups. I'm having big doubts now on BTRFS , is my disk broken ??? Is my data in danger ???

BT
