Upgrade F16 -> F17 doesn't find F16 LVM installation

Hi,

I'm trying to upgrade from F16 to F17 (both 64 Bit) but F17's anaconda doesn't find my F16 LVM installation (tried both preupgrade as well as DVD upgrade).

My layout is quite simple:
/dev/sdb1 on /backup type ext4
/dev/sda1 on /boot type ext4
/dev/mapper/vg_neptun-lv_home on /home type ext4
/dev/mapper/vg_neptun-lv_root on / type ext4
/dev/mapper/vg_neptun-lv_swap swap

After anaconda is examinig the storage it states that it cannot find an installation or the installation is too old. On tty2 (Alt-Ctrl-F2) it states
WARN storage: mount of loop1 as ext4 failed: mount failed: (32, 'mount: /dev/loop1 is already mounted or /mnt/sysimage busy')

lvscan shows that the LVMs are inactive so I also tried to activate them with vgchange -aly after anaconda showed the error message and clicking back (in the graphical installer) with no luck.

Additionally I attached some logs.

Any hint is appreciated!

Thanks in advance,
Al
