Title:
  btrfs-tools package in 12.04 is very old, doesn't support scrub

Status in “btrfs-tools” package in Ubuntu:
  Confirmed

Bug description:
  Background:
    btrfs scrub functionality was implemented in the 3.0 kernel, which was shipped with 11.10. This allows the btrfs filesystem to repair data corruption in RAID1 and RAID10 data layouts.

  Unfortunately, 11.10 didn't ship with the updated btrfs-tools package
  to actually use this functionality. Looking now, 12.04 is also set to
  ship with an old btrfs-tools package (0.19+20100601-3ubuntu3). This is
  very strange, since Debian/testing upstream includes a more recent
  package that includes the scrub functionality:

    http://packages.debian.org/wheezy/btrfs-tools
    btrfs-tools_0.19+20111105-2.dsc

  In my testing, the upstream Debian package can be installed directly
  on 12.04 (and on 11.04 with an e2fsprogs backport), and it works
  correctly.

  Given that this updated userspace package is critical to repairing
  data corruption on btrfs filesystems, and that 12.04 is a long term
  service release, I'd highly recommend that it be flagged for inclusion
  in 12.04.
