In your case "btrfs filesystem df" seems to show something about specia= l =20 informations and their need of space but nothing about used space or =20 available space. Some weeks ago there has been a thread about the informations of "df", = =20 "btrfs filesystem df" and "btrfs filesystem show"; most times there may= =20 be shown the "at least available space". Viele Gruesse!
