[Bug 757631] Re: grub-probe fails on lvm-encrypted install with btrfs

[Launchpad Bug Tracker]

This bug was fixed in the package grub2 - 1.99-7ubuntu1

---------------
grub2 (1.99-7ubuntu1) oneiric; urgency=low

  * Resynchronise with Debian.  Remaining changes:
    - Adjust for default Ubuntu boot options ("quiet splash").
    - Default to hiding the menu; holding down Shift at boot will show it.
    - Set a monochromatic theme and an appropriate background for Ubuntu.
    - Apply Ubuntu GRUB Legacy changes to legacy update-grub script.
    - Fix backslash-escaping in merge_debconf_into_conf.
    - Remove "GNU/Linux" from default distributor string.
    - Add crashkernel option.
    - Bypass menu unless other OSes are installed or Shift is pressed.
    - Allow Shift to interrupt 'sleep --interruptible'.
    - Reduce visual clutter in normal mode.
    - Remove verbose messages printed before reading configuration.
    - Suppress kernel/initrd progress messages, except in recovery mode.
    - Show the boot menu if the previous boot failed.
    - Don't generate device.map during grub-install or grub-mkconfig.
    - Adjust upgrade version checks for Ubuntu.
    - Suppress "GRUB loading" message unless Shift is held down.
    - Adjust versions of grub-doc and grub-legacy-doc conflicts.
    - Fix LVM/RAID probing in the absence of /boot/grub/device.map.
    - Look for .mo files in /usr/share/locale-langpack first.
    - Build-depend on qemu-kvm rather than qemu-system for grub-pc tests.
    - Check hardware support before using gfxpayload=keep.
    - Put second and subsequent Linux menu entries in a submenu.
    - Preferred resolution detection for VBE.
    - Set vt.handoff=7 for smooth handoff to kernel graphical mode.
    - Update default/grub.md5sum to include maverick's default md5sum.
    - Add nomodeset to Linux kernel arguments in recovery mode.

  * Cope with btrfs / inside an encrypted block device (thanks, alexeagar;
    LP: #757631).
  * Merge from Ubuntu:
    - Give up scanning partitions after ten consecutive open failures
      (LP: #787461).

grub2 (1.99-6) unstable; urgency=low

  [ Colin Watson ]
  * Update Vcs-* fields for Alioth changes.
  * Backport from upstream, removing the need for Breaks: udev (<< 168-1):
    - Don't stat devices unless we have to.

  * Catalan (Jordi Mallach).

grub2 (1.99-5) unstable; urgency=low

  [ Colin Watson ]
  * Change grub2/linux_cmdline and grub2/kfreebsd_cmdline descriptions to
    indicate that the command line is allowed to be empty, since this is a
    common source of confusion (thanks, Jordan Uggla).
  * On non-Ubuntu-derived systems, add Breaks: udev (<< 168-1) to
    grub-common, for the sake of (some?) users without initrds (closes:
    #627587).

Bug description:
  Binary package hint: grub2

  Install was done using the "Setup encrypted LVM" option, simply
  changing ext4->btrfs

  Grub fails to add the "rootflags=subvol=@" to the kernel boot options,
  making the system stop at initramfs on boot, unless added manually, at
  which point it seems to boot fine.

  When booted grub-probe seems not to work, which I assume is the core issue:
  arand at nnb:~$ sudo grub-probe /
  grub-probe: error: no such disk.
