i did some testing using btrfsprogs version 0.18
after doing mkfs.btrfs with version 0.18 , the disk is mountable by the
so it seems btrfs tools are upgraded but also needs a kernel update to 2.6.31
or backport of the new format to 2.6.30
should i open a case for this or is 2.6.31 kernel still in de scope of
openSuSE 11.2 ?

looking around on linux kernel mailing list i found this thread
it mentions that using new version .19 of tools on "old" 2.6.30 kernel will
not work because of change in internal data storage structure.
factory is using following versions :
btrfs tools: btrfsprogs-0.19-2.2
There is a backport for 2.6.30 kernels. so is this backport included in
openSuSE kernel or do we need to downgrade btrfsprogs ?

i'm trying to test the new btrfs filesystem in opensuse factory.
i have currently followin kernel and btrfs packages installed:
i'm running this in VirtualBox 3.0.2
i can create btrfs on /dev/sdb1 but when i mount it , i get following
linux-m4pt:/home/luc # mount -vvvv /dev/sdb1 /data
mount: fstab path: "/etc/fstab"
mount: mtab path: "/etc/mtab"
mount: lock path: "/etc/mtab~"
mount: temp path: "/etc/mtab.tmp"
mount: UID: 0
mount: eUID: 0
mount: spec: "/dev/sdb1"
mount: node: "/data"
mount: types: "(null)"
mount: opts: "(null)"
mount: you didn't specify a filesystem type for /dev/sdb1
I will try type btrfs
mount: mount(2) syscall: source: "/dev/sdb1", target: "/data",
filesystemtype: "btrfs", mountflags: -1058209792, data: (null) mount:
wrong fs type, bad option, bad superblock on /dev/sdb1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
looking in dmes , i see following :
[ 3086.053308] device fsid 3446bae7efc3e33f-daf4e58f9a3617ae devid 1
transid 7 /dev/sdb1 [ 3086.054435] BTRFS: couldn't mount because of
unsupported optional features (1). [ 3086.054593] btrfs: open_ctree
checking the device seems to be ok
