Basically my question is : Is there anyway I can turn this broken FS
into a sane FS using « btrfs repair » EVEN if this causes data losses ?
I can afford some data losses of this backup disk (next backup will fix
missing files)
But I DO NOT want to lose (or have to recreate) the complete FS with all
its subvols and snapshots, which I have no other disk to copy to currently.
So I can accept a « fix with losses », but not a « well you need to
reformat the disk completely »...
Kind regards.
