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.
There''s a daily kernel build PPA: http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/2011-03-08-natty/ Sorry to note, but have you even tried googling for it?

I was hoping to not upgrade a whole kernel to the current development kernel but instead just update btrfs to as new as I can get with a 2.6.32 kernel. Just trying to keep the ripple effect to a minimum.> The wiki is your friend. :)Indeed. b.

That''s a very early kernel, in btrfs terms.That may be true, but as someone who''s been running btrfs as /home on laptop SSD''s for over 2 years now the reports from people using later kernels worried me enough to not go past 10.04 on it. However, the impression I''m getting now is that 2.6.38 is looking a lot more solid for btrfs than recent kernels and so I''m looking forward to testing that out when 11.04 comes out! cheers, Chris -- Chris Samuel : http://www.csamuel.org/ : Melbourne, VIC This email may come with a PGP signature as a file.
