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?

Ouch. That's a *very* early kernel, in btrfs terms. There are a
significant number of serious bugs that have been fixed since then.

There's Ubuntu kernel PPAs listed on the btrfs wiki:
https://btrfs.wiki.kernel.org/index.php/Getting_started#Ubuntu_Linux
The wiki is your friend. :)

Yeah, that's my understanding also.

Bugs in btrfs or other related kernel bugs?

Indeed. 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.

Indeed.

Well, both, but I was specifically referring to btrfs.

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
