Hello, remind of the probem : by some manipulation quite uncontrolled, I ended with a pv of a vg completly unconsistant. I finally modified the vgda to have a vg consistant enough to restart. And I activate the vg, and my data is now available. Thanks to Heinz. But I found and interresting bug on vgimport that mixed the data of an active vg on the system and the vg I imported. The condition to have this problem is to have the name of an active vg identical to the name of the vg to be imported. As soon as I know the end I inform you.
