[Bug 1001076] Re: system fails to boot if btrfs has certain options in /etc/fstab

This is because the btrfsck tool doesn't support compression. Upon
mountall,

fsck from util-linux 2.20.1
couldn't open because of unsupported option features (8).
fsck.btrfs: disk-io.c:679: open_ctree_fd: Assertion `!(1)' failed.
fsck: Warning... fsck.btrfs for device /dev/mapper/nogroanhomer-home exited with signal 6.

Knowing that, I've found the bug #748340; this is a dupe.

Title:
  system fails to boot if btrfs has certain options in /etc/fstab

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

Bug description:
  I have btrfs running on second  harddrive (Not the root partition). I
  use 'compress=lzo' and I have set 'pass' to '2' so that the OS will
  check the volume at boot time.

      # <file system> <mount point>   <type>  <options>       <dump>  <pass>
      UUID="abcdefg" /btrfs   btrfs   defaults,compress=lzo   0   2

  I am unsure if 'compress=lzo' has anything to do with this error.

  However, if I do this then Ubuntu fails to boot. The error presented
  on the screen is:

      "Serious errors were found while checking the disk drive for[/btrfs].
      "Press I to ignore, S to skip mounting, or M for manual recovery."

  The workaround is to edit /etc/fstab and set 'pass' to '0', which
  disables the fsck.

  (Assigning to btrfs-tools initially. Not sure if that is the correct
  package.)
