I agree that this is problematic for applications. But in BTRFS this has technical reasons: https://btrfs.wiki.kernel.org/index.php/FAQ#Why_are_there_so_many_ways_to_check_the_amount_of_free_space.3F https://btrfs.wiki.kernel.org/index.php/FAQ#Why_is_free_space_so_complicated.3F Basically: Its too flexible for correct free space display. And then this leads to something like: merkaba:[…]/btrfs-progs-unstable> ./btrfs fi df /home Disk size: 223.52GB Disk allocated: 208.02GB Disk unallocated: 15.50GB Used: 197.13GB Free (Estimated): 26.38GB (Max: 26.38GB, min: 18.63GB) Data to disk ratio: 100 % Yeah, estimated.
