Bug Description
I have a btrfs RAID5 on 9 external USB3 drives. When I started the 16.04 beta1 Lubuntu live CD, the btrfs volume (named Backup) was mounted 8 times:

I have the same thing, with a primary mount at /media/barak/foo and duplicate mounts at /media/barak/foo1 and /media/barak/foo2, where it is a two-disk btrfs filesystem. I can umount the extras and things still seem okay.
