It takes too long. So what would be the solution ? IMHO yes, having to full backup then reformat then full restore is impractical for big FSes. Especially if they have a lot of subvols. Also most private individuals do not have enough disks to perform a full backup of their RAID NAS, etc. And a FS “repair” is long and often inefficient. I believe that we should have a repair tool that can fix a filesystem metadata and make it clean and usable again even if this is at the cost of losing a whole directory tree or subvols or whatever. But it would be better to lose clearly identified things and resume with a working FS and a list of files to be restored, rather than being unable to repair and having to reformat everything and restore everything...
