Ok - just for your information the messages of my system, created with

   mkfs.btrfs -d raid0 -m raid1 ...

# btrfs filesystem show
Label: 'MMedia'  uuid: 120b036a-883f-46aa-bd9a-cb6a1897c8d2

----------------------------------------

I don't know what's the meaning of the type "DUP" (instead of "RAID0" o=
r =20
"RAID1" in my example).

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!
