[Bug 880645] Re: "btrfs device delete /dev/sdaX /" fails with error "ERROR: error removing the device '/dev/sdaX'"

[Thorsten Zitterell]

I installed the mainline kernel from http://kernel.ubuntu.com/~kernel-
ppa/mainline/v3.4-precise/ and compiled the btrfs tools from
git://git.kernel.org/pub/scm/linux/kernel/git/mason/btrfs-progs.git.

Then, I could remove the second drive after converting raid1 back to
raid0:

% ./btrfs balance start --force -mconvert=raid0 /

Title:
  "btrfs device delete /dev/sdaX /" fails with error "ERROR: error
  removing the device '/dev/sdaX'"

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

Bug description:
  What I did to cause this:

  Installed ubuntu using btrtfs root.
  Added a device with 'btrfs device add /dev/sda9 /'
  Balanced the file system with 'btrfs filesystem balance /'
  Tried to remove a device with 'btrfs device delete /dev/sda9 /'. Noticed that I got the error "ERROR: error removing the device '/dev/sda9'".

  (Unfortunately, I'm not sure how to get more information on the
  problem.)
