I am using btrfs on Ubuntu's LTS kernel (2.6.32-22-generic) and have
updated the btrfs-tools to 0.19+20101101-1~lucid1. I have also built
the latest from
git://git.kernel.org/pub/scm/linux/kernel/git/mason/btrfs-progs-unstable.git.
The problem is that I don't get anything from btrfs fi df $mountpoint.
i.e., for the btrfs filesystem mounted at /mnt/btrfs-test/
# ./btrfs fi df /mnt/btrfs-test/
#
See, no output. Is my kernel module too old for that feature? Maybe it is:
stat64("/mnt/btrfs-test/", {st_mode=S_IFDIR|0755, st_size=72, ...}) = 0
open("/mnt/btrfs-test/",
O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY|O_CLOEXEC) = 3
fcntl64(3, F_GETFD) = 0x1 (flags FD_CLOEXEC)
ioctl(3, 0xc0109414, 0x999c320) = -1 ENOTTY (Inappropriate ioctl
for device)
exit_group(-1) = ?
If my kernel module is too old, anyone know of a successful backport of
a newer btrfs for Ubuntu Lucid? In a PPA or otherwise?
Cheers,
b.
