Kernel 2.6.35.8:

# btrfs filesystem df /srv/MM
Data: total=2.39TB, used=2.37TB
Metadata: total=5.25GB, used=3.51GB
System: total=12.00MB, used=188.00KB

Kernel 2.6.37-rc4:

# btrfs filesystem df /srv/MM
Data, RAID0: total=2.39TB, used=2.37TB
System, RAID1: total=8.00MB, used=188.00KB
System: total=4.00MB, used=0.00
Metadata, RAID1: total=4.25GB, used=3.51GB
Metadata, DUP: total=1.00GB, used=2.33MB

Hope it helps!

Viele Gruesse!
