The asciidoc conversion was done on a development branch and there are
portions of text that do not reflect the code.

-The command 'btrfs filesystem df' is used to query how many space on the 
-disk(s) are used and an estimation of the free
-space of the filesystem.
-The output of the command 'btrfs filesystem df' shows:
-
-`Disk size`::::
-the total size of the disks which compose the filesystem.
-
-`Disk allocated`::::
-the size of the area of the disks used by the chunks.
-
-`Disk unallocated`::::
-the size of the area of the disks which is free (i.e.
-the differences of the values above).
-
-`Used`::::
-the portion of the logical space used by the file and metadata.
-
-`Free (estimated)`::::
-the estimated free space available: i.e. how many space can be used
-by the user. The evaluation cannot be rigorous because it depends by the
-allocation policy (DUP, Single, RAID1...) of the metadata and data chunks. +
-If every chunk is stored as "Single" the sum of the free (estimated) space
-and the used space  is equal to the disk size.
-Otherwise if all the chunk are mirrored (raid1 or raid10) or duplicated
-the sum of the free (estimated) space and the used space is
-half of the disk size. Normally the free (estimated) is between
-these two limits.
-
-`Data to disk ratio`::::
-the ratio betwen the logical size (i.e. the space available by
-the chunks) and the disk allocated (by the chunks). Normally it is 
-lower than 100% because the metadata is duplicated for security reasons.
-If all the data and metadata are duplicated (or have a profile like RAID1)
-the Data to disk ratio could be 50%.
