Comment 17 for bug 1005854

I have a similar problem. I use LVM and I have several logical volumes with Ubuntu chroots and LXCs:

root@nsn7:~# lvs
  LV VG Attr LSize Pool Origin Data% Move Log Copy% Convert
  games vg0 -wi-ao-- 50,00g
  home vg0 -wi-ao-- 46,56g
  lucid-lxc vg0 -wi-a--- 500,00m
  lucid_i386_chroot vg0 -wi-a--- 5,00g
  nova vg0 -wi-a--- 10,00g
  postgresql vg0 -wi-ao-- 79,31g
  precise vg0 -wi-a--- 500,00m
  precise_i386_chroot vg0 -wi-a--- 5,00g
  quantal_i386_chroot vg0 -wi-a--- 5,00g
  raring-lxc vg0 -wi-a--- 500,00m
  raring-temp vg0 -wi-a--- 500,00m
  raring_i386_chroot vg0 -wi-a--- 5,00g
  root vg0 -wi-ao-- 1,86g
  swap vg0 -wi-ao-- 7,91g
  var vg0 -wi-ao-- 18,62g
  virt vg0 -wi-ao-- 50,00g

My fstab:
proc /proc proc nodev,noexec,nosuid 0 0
/dev/mapper/vg0-root / ext4 errors=remount-ro,barrier=0 0 1
# /boot was on /dev/sda1 during installation

Attached is what unity shows.
