[linux-lvm] vgscan cant find my vg

[Rene Schumann]

Hello!

I have a volumegroup with name vg01 (sda1,sda2) since long time wich hold all 
my userdata.
Since yesterday my OS cant find this vg anymore.
I remember the last thing was i did add hda9 to vg01.
I did this while installing Mandrake9.0 for testing.
I couldnt find a error from LVM but vgscan fails to find my vg.
Laterly i created a second Volumegroup with name vg (hda9) but vg01 still not 
working.
I also did a vgcfgrestore of vg01 from a 2 weeks old backup but it changes 
nothing. 
It would be hard for me if i loose my data.
Can someone please help me?
