Bonjour.
J'ai lancé l'extension d'un RAID 6 sur un TS-809 FW 4.2 1118 et, après une bonne minute, le message "expansion failed" est apparu et le volume RAID 6 est maintenant inaccessible et démonté.
Apparemment, le problème vient du superblock qui est abîmé.
Est-ce que quelqu'un sait comment remonter le Raid ?
Quelques infos:
