In the past [1] I proposed the following approach. $ sudo btrfs filesystem df /mnt/btrfs1/ Disk size: 400.00GB Disk allocated: 8.04GB Disk unallocated: 391.97GB Used: 11.29MB Free (Estimated): 250.45GB (Max: 396.99GB, min: 201.00GB) Data to disk ratio: 63 % The space was given in terms of "disk space" and in terms of "filesystem space". Other that there is an indication of an estimation of the free space, with the pessimistic and optimistic values.
