Comment # 11 on bug 957046 from Stefan Hundhammer

So those additional LVs are already there during probing, they are just not
shown in the truncated "vgdisplay" output:

So the complete LV list is:

LV /dev/external/backup
LV /dev/sdb1_vg/data
LV /dev/sda2-vg/os_root
LV /dev/sda2-vg/lvol0
LV /dev/sda2-vg/vg-home
LV /dev/sda2-vg-os_leap

They all exist before the installation.
