**Problème de récupération de mes données après sinistre**
Bonjour Chers Tous,
Je dispose d'un serveur dédié avec 3 disques (**sda**, **sdb** et **sdc**) montés en RAID 5. Les partitions en RAID sont **md2**, **md3** et **md5** .
Il se passe que le disque **sda** est défectueux. Aussi, le serveur est en ce moment en mode RESCUE.
Avant le remplacement de ce disque défectueux, je tente de faire sauvegarde une sauvegarde de mes données mais malheureusement je ne retrouve pas mes données sur les partitions **md2**, **md3** et **md5** tous dans le **/dev**
Je ne retrouve pas non plus ma Base de Données dans toutes l'arborescence.
Prière m'assister pour la récupération de mes Données SVP.
Cordialement.
**PS** : Ci-dessous le résultat de la commande **parted -l** en mode rescue.

Bonjour @SimpliceA
Aviez-vous pensé à faire des sauvegardes sur un PC, un disque USB chez vous ?
Bonjour Gaston,
Malheureusement, je n'ai aucune sauvegarde locale en ma possession.
Comment puis-je procéder pour faire une sauvegarde en mode rescue ?
La récupération n'est jamais garantie. Raid-5 devrait survivre au crash de un disque, mais pas deux disques. Dans ce cas tout est détruit et vous devez repartir sur un backup externe.
Or si votre serveur est en rescue, c'est qu'il ne boote plus ?
Que donne la commande: lsblk ?
Que donne la commande smartctl -a /dev/sda (et puis sdb et sdc)
Que donne la commande: cat /proc/mdstat ?
Il y'a **un seul disque** qui est défectueux.

Votre /dev/sda est donc crashé.
A ce stade, il n'a pas encore été remplacé, c'est correct ?
Vous avez le n° de série du disque défectueux dans la commande smartctl.
Pour signaler le crash disque, vous le communiquerez à OVH pour vous assurer qu'ils remplacent le bon disque.
Effectivement, le disque n'a pas encore été remplacé
Il faut faire remplacer votre disque maintenant.
OVH est très efficace au niveau du bare metal.
Après il faudra rebuilder, votre partition bootable est en raid-1 (miroir) sur les 3 disques, on devra peut-être se battre avec grub, ou pas... voyez sur le forum, dans les conversations les plus récentes qui parlent de grub.
Le temps que votre disque soit remplacé, et de re-vérifier que les sda, sdb et sdc ont conservé leur lettre, et étudier les commandes sgdisk pour recopier la partition table, mdadm pour reconstruire votre raid.
Attention, toute erreur se paie cash et peut amener à la perte irrémédiable de tous vos disques.
OVH me demande d'effectuer une sauvegarde de mes données avant qu'il ne procède au remplacement du disque.
Comment procéder ?
Faites donc, vous êtes en mode dégradé.
C'est vous le locataire de la machine et qui devez avoir pris toutes vos dispositions (relisez votre contrat si vous avez un doute)
N'aurais-tu pas la procédure pour effectuer la sauvegarde dans une telle condition ?
C'est avant qu'il aurait fallu y penser.
Je n'ai aucune idée du volume à copier, ni des autres supports à ta disposition.
Je comprends la position d'OVH (tout comme n'importe quel hébergeur) qui n'endosse pas la responsabilité en cas de perte de données lors d'une intervention.
Avoir un serveur sans plan de récupération c'est une faute professionnelle grave, et de telles situations nuisent à la réputation de notre profession.
Je n'interviendrai donc plus dans cette conversation, sauf éventuellement des questions techniques précises mais qui trouvent de toute façon réponse un peu partout sur internet.
