Very nice! I updated to 5.14 and mounted with "-o ro,rescue=all” and yes, I can see all data now.
I guess this is just for data recovery, not a permanent mount option, right?
I should rescue the data and format the disc again, right?

It is a file on a SAS External Physical Volume that is formatted in Mac OS Extended and attached to the Parallels as an additional disc, then formatted inside linux with btrfs
BTW, I think now I know exactly what I did wrong to get to this stage.
I suspended my Virtual Machine with all discs still mounted. Then I started a new Virtual machine with the same discs attached and this confused the discs.
Should avoid this.
