Switching to a new filesystem is never a task that is done with a light heart. We have our own trusted good old filesytem, that has maybe limits in features and performance, but has never let us down. New filesystems are available, and they promise wonderful things. But as much as we are fascinated by them, the big Q “Should I trust it?” comes to mind when we just start thinking about moving to a new filesystem. In Linux, this question arises everytime BTRFS is involved.
