If that is inappropriate with btrfs - well, I'd say again, then this fs is not appropriate for the things a normal user would do.[...]
There was once a time when ext4 was where btrfs is now: How on earth would anyone use it when ext2 "just works"? Right? Right? :-)
Well, as far as I remember the issues with ext4 didn't last long, whereas btrfs is still problematic after all this time. Sure, it is more advanced.
New technology comes with new features, new solutions and new ... surprises. I rarely had problems with btrfs (meaning: never lost data). I just ran once into "disk full" which made me pull my hair until I understood the issue.
I did lose test data. Ie, not real data, but I managed to crash the filesystem beyond repair. The crash was repeatable. This particular issue has been solved since.
A better solution would be to patch "df" to show two values (10% full (50% incl. snapshots)). We wouldn't figure that out without giving btrfs to many people who then scream bloody hell at the decisions which seemed reasonable to designers.
Yes, I think df should be patched to give info pertinent to btrfs, perhaps after giving an option, if the change would break scripts that parse result.
At the end of the das I would like to rise the question again: "btrfs has new and interesting features". Well, for whom? Am I offered a car with 5 rather than 4 wheels now? Does this help me getting better from location A to location B?
In this case, btrfs has a feature where you can rewind time to before the accident. Is that useful? Yes. For many people? Oh, yes! Hard to find? Maybe. Can it confuse even experts? Sure. Is it a bug? ... No. Is it better than ext4? Depends.
Yes, I agree it is a very useful feature. I simply do not trust it. Also, on practical reasons, I would have to repartition my disks to give way more space to the root partition, and I'm not doing that work anytime soon. -- Cheers / Saludos, Carlos E. R. (from 42.2 x86_64 "Malachite" (Minas Tirith))
