+# Exécuté avec succès le 2021-11-09 par abenmiloud sur un serveur OVH STOR-1 Gen 2
+
+# Le script suppose que :
+# * il y a 2 disques NVMe en RAID logiciel pour le système
+# * il y a 4 disques SATA en RAID logiciel
+# * le serveur démarre en UEFI
+# * on va reconstruire toute la table de partitionnement (GPT) du serveur
+# Enfin un fstab est généré, le raid est configuré, lvm2 est installé,
+# grub et le kernel sont réinstallés.
+
+# Avant de commencer, consulter les disques pour vérifier les noms
+lsblk
+
+# Ne pas tout copier-coller d’un coup !
+# Have fun!
