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. ॐ -- Swâmi Petaramesh <swami@xxxxxxxxxxxxxx> PGP 9076E32E
