Hello,

i'm trying to test the new btrfs filesystem in opensuse factory.

i have currently followin kernel and btrfs packages installed:
kernel-default-2.6.30-10.1
btrfsprogs-0.19-2.2

i'm running this in VirtualBox 3.0.2
i can create btrfs on /dev/sdb1 but when i mount it , i get following error :

linux-m4pt:/home/luc # mount -vvvv /dev/sdb1 /data
