Hello,
It seems this might be a bug.
00:24:51 rrs@champaran:/mnt/btrfs $ cp /home/rrs/PDds73yDCNo.flv .
cp: writing `./PDds73yDCNo.flv': No space left on device
So, I have an error of no free space.
00:24:56 rrs@champaran:/mnt/btrfs $ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/LocalDisk-ROOT
110G 90G 19G 84% /
tmpfs 1.5G 12K 1.5G 1% /lib/init/rw
udev 1.5G 364K 1.5G 1% /dev
tmpfs 1.5G 248K 1.5G 1% /dev/shm
/dev/sda2 942M 121M 812M 13% /boot
/dev/mapper/VgTest-lvol0
32G 21G 12G 63% /mnt/btrfs
But that is not what df wants to report.
00:25:01 rrs@champaran:/mnt/btrfs $ sudo btrfs-show
failed to read /dev/sr0

Btrfs Btrfs v0.19
And looks same on btrfs-show.
I am running a 2.6.35 kernel with btrfs-tools version 0.19+20100601-3 on
Debian.
