First, you mentioned the crucial bit of information (that it's a btrfs
filesystem) only at the end. Also, you've left out important things such
as your running kernel and (to a lesser extent) version of btrfs-tools
(or btrfs-progs in newer systems).

As others have pointed, btrfs is the culprit. Take a look at these links
to try to understand what might have happened:

https://btrfs.wiki.kernel.org/index.php/Problem_FAQ#I_get_.22No_space_left_on_device.22_errors.2C_but_df_says_I.27ve_got_lots_of_space
