[linux-lvm] problem after vgextend

[Jean-François Rousseau]

Hi,

I have a big problem.. I have an LVM with 2 80Go disk. I wanted to upgrade one to a 200Go. So I did as the how-to said: pvcreate and av vgextend. Then I rebooted. Since then I have been unable to activate the volume group. There is always the same error. I've searched the list and tried a couple of command. uuid_fix didn't work (altough it said it did) and I can't find any .conf file.

Is there any way I could activate this supid voulume group ?

thanks in advance.
