Sorry, j'étais à l'étranger pour le boulot.

Non, je ne pense pas avoir touché à quoi que ce soit sur les disques.

J'ai lancé un ddrescue de tous le M-SATA avant de partir et je vois que seul 30M serait corrompus.

J'imagine que c'est la que se trouvait LVM.

Maintenant, j'aimerais bien accéder à mes données...

Un fdisk -l me montre bien mes partitions dans le fichier de travail (une copie de l'original).

J'ai tenté un losetup --offset pour charger la partition dans /dev puis la monter, ce qui ne marche évidement pas puisque la partition est de type LVM.

Donc j'ai tenté un vgcreate, lvcreate en renommant mon VG et mon LV d’après mes souvenirs (donc comme Debian les génère: NOM_MACHINE-vg).
Je ne sais pas si les noms ont une importance.

J'ai donc un LV, mais je n'arrive pas à le monter via mount.

J'avoue que je ne maîtrise pas du tout les outils que je tente d'utiliser et que je les utilise donc probablement mal.

Je suis ouvert à toute proposition...

Ce qui m'inquiète, c'est que dans le post, le gars voit son VG et son LV.

Moi je vois rien du tout...

Et j'ai peur de ne pas réussir à monter cette partition.

Apparement, l'output de cette commande a changé:
