Bonjour,

Voila, je pense rencontrer un problème si je puisse dire.

Celà fait quelques mois que j'ai mon nouveau serveur dédié chez OVH SoYouStart pour être exact, dans l'offre que j'ai choisi j'ai d'afficher SoftRaid 2x2To SATA (l'offre a changé depuis, il est passé à SoftRaid 3x2To SATA).

Ce que je veux

J'aimerai savoir comment utiliser le second disque dur fourni, car si j'ai bien compris je dispose de 2 disques dur de 2To et je risque d'en avoir besoin un moment donné.

Ce que je fais

Voici les divers commandes que j'ai lancer pour avoir des infos sur mes disques :

J'avais un peu cherché sur internet, mais les 2 dernières commandes me retourne un résultat inattendu pour moi.

Quelqu'un aurai une idée de comment faire ?
Dois-je contacter le support pour plus d'infos ?

Merci d'avoir pris de temps de lire mon poste.

A mon avis c'est un RAID disque que tu, pour protéger les données en cas de perte de disque, tu n'as pas 3x2To mais 2To en RAID sur 3 disque.

edit: Oui c'est bien ca, je viens d'aller voir les offres soYouStart et tu a bien marqué SoftRaid 3x2 TO donc tu n'as que 2To de stockage et tu a une redondance des donnée en RAID sur 3 disque pour sécuriser l'intégrité des données.

Ah d'accord ça explique pourquoi ils sont identiques en terme de partition, merci !

De rien :-)
