Hi, Since non-durable appears to be controversial, let's consider the case without that aspect. Since the introduction of ext4, some apps/users have had issues with file corruption after a system crash. It's not a bug in the FS AFAIK and it's not exclusive to ext4. Writing a temp file, fsync, rename is often proposed. But how does one preserve meta-data, including file owner?
