Récupération données disque Raid 1 issu d'un NAS Netgear

Chon78

Bonjour à tous,
Notre NAS Netgear ReadyNas Pro 2 RNDP2000 (Raidiator 4.2.31) est crashé, il ne monte plus les volumes et donc plus d'accès aux données qui sont dessus.
Ce NAS était équipé de 2 disques de 2To chacun montés en Raid 1.
J'ai donc sorti les DD et connecté un des 2 disques à mon PC sous Xubuntu (config en signature) via un boitier USB. Mon PC étant un mini PC, je ne peux pas branché en direct sur des nappes intérieures et je n'ai qu'un boitier à dispo pour le moment. Explication pour le "un des 2 disques".
Une fois connecté, le volume est bien sûr invisible et GParted me rend ceci pour ce disque :

Bien sûr, ce qui m'intéresse devrait logiquement se trouver sur la partie "Non allouée".
Pensez-vous donc que quelque chose puisse être tenté pour une récupération ?

Je ne sais pas si c'est du Raid matériel ou logiciel.
J'ai installé mdadm et lvm2, mais mes compétences étant limitées, je préfère demander conseil à ce stade plutôt que faire une chonnerie.

Je remercie d'avance tous ceux qui pourront m'apporter de l'aide.

Je vais malheureusement être pas mal absent ce WE, je ne vais donc pas forcément être très réactif aux différentes réponses et questions posées et je m'en excuse par avance.

Bien cordialement

Bonjour à tous,

plus je me renseigne sur le sujet, plus je me dis que la partie du disque vue comme "non allouée", c'est pas bon du tout... :mad:

Brunod

Et je me dis que s'il y avait un problème de montage, c'était peut-être dû à ce disque... Donc que dit l'autre ?

??

Bonsoir.
La première des choses est de faire un rapport smartct de chacun de tes deux disques pour avoir une idée du moins âbimé.

paragraphe 1 et 3.2 ou 3.3 de smartctl https://doc.ubuntu-fr.org/smartmontools

Ensuite il faudra trouver comment le nas a organisé la structure disque...... avant de dire que cela ne va pas.

Tu donneras aussi ce retour pour éviter les captures d'écran

sudo lsblk -o size,name,fstype,label,mountpoint

Chon78

Bonsoir à tous et merci pour vos réponses.

@Brunod, Je n'ai pas de 2e lecteur à dispo, j'ai donc déconnecté le 1er DD, connecté le 2e à sa place et redémarré le PC.
GParted me donne exactement la même table.

@?? Je vais regarder ça dès que je peux me poser.

Je vous tiens au courant. 😉

La commande :

sudo lsblk -o size,name,fstype,label,mountpoint

renvoie ça :

sudo lsblk -o size,name,fstype,label,mountpoint

??

et le smartctl? tu feras disque par disque.
Tu peux déjà commencer à prospecter pour l'achat d'un disque d'au moins la même taille. Sinon deux.

Bonjour à tous,

Désolé pour les contretemps, je suis en déplacement.

Je fais les tests smartctl dès que possible.

Mon diagnostic : Tes données sont en parfait état. Je ne comprends pas pourquoi ton NAS a cessé de les utiliser.
En regardant de plus près, il est possible qu'il ait fait du préventif en disant que cela allait casser car il y a quand même deux lignes inquiétantes

195 Hardware_ECC_Recovered  0x001a   020   004   000    Old_age   Always       -       103413624

https://fr.wikipedia.org/wiki/Self-Monitoring,_Analysis_and_Reporting_Technology a écrit195 0xC3 Hardware ECC Recovered NC N/A Temps entre les erreurs corrigées par code correcteur (?) (augmente et diminue, une faible valeur est probablement mauvaise).

Je résume ainsi. Je mets 100 litres d'essence dans mon réservoir. Que dois-je faire lorsqu'il n'en reste plus que 4 ou 8?
sachant qu'à zéro c'est la panne sèche

Je vois que mettre au repos forcé l'un des disque lui a redonné 20 litres de carburant,

Pour le moment, je ne sais pas t'en dire plus pour l'endroit défaillant mais ce n'est pas la partie des plateaux des disques.
Ce n'est peut-être pas le firmware des disques (deux bien abîmés!) La connectique en amont? ( Le NAS lui même)
Voir en amont du NAS ?

Merci @??

Tout espoir ne semble donc pas perdu. Tu dis que les plateaux te semblent intègres et que les données doivent être dessus.
Mais pourquoi Gparted considère ces 1.8 To non alloués sur les 2 disques ?

??

Bonjour.
Sur ce point je n'ai pas de réponse précise.
Le logiciel de ce nas pourrait ne pas appliquer à 100% la logique MDADM
Une premiere partition dans laquelle il stocke son logiciel
Une seconde partition dans laquelle il va mémoriser les lieux de stockage de tes données
Le reste étant destiné à stocker tes données en format propriétaire afin de te rendre captif de ce modéle.
Ou alors le logiciel a déconné et a élimimé tes données.

Ce dont, je suis sur, c'est que tes deux disques ne sont pas à remplacer, alors que c'est le cas habituel.

S'il n'a pas stocké tes données dans un format propriétaire, tu pourrais utiliser photorec dans le seul but de voir ce qu'il y a dans la partie non allouée. https://doc.ubuntu-fr.org/photorec
