Raid 5 avec mdadm, superblock corrompu
Bonjour,
J'ai depuis un an monté un serveur nas maison sous ubuntu. Il est équipé de 3 disques de stockages, et le raid 5 est créé via mdadm.
Je suis coincé depuis quelques mois sur un soucis, et je suis venu à bout de toutes mes idées.
Je n'arrive plus à accéder au système de fichiers. Pourtant mdadm indique que les Superblocks sont persistents, mais quand j'analyse chaque disque, on m'indique que les superblocs sont défectueux et qu'il faut que je trouve un superblock de backup.
Bien évidemment, c'est tombé la semaine où je comptais mettre en place des backups réguliers automatisées des données…
Si quelqu'un sait comment me sortir de cette affaire ou m'indiquer d'autres manipulation à tester, je suis preneur.. merci beaucoup !
Je met ici quelques informations:

Re : Raid 5 avec mdadm, superblock corrompu
Bonjour geole !
Merci pour cette réponse, voici les informations demandées :
➜ sudo fsck /dev/md127
fsck from util-linux 2.37.2
e2fsck 1.46.5 (30-Dec-2021)
ext2fs_open2: Bad magic number in super-block

fsck.ext2: Bad magic number in super-block while trying to open /dev/md127
The superblock could not be read or does not describe a valid ext2/ext3/ext4
filesystem. If the device is valid and it really contains an ext2/ext3/ext4
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>

Re : Raid 5 avec mdadm, superblock corrompu
Bonjour
On va essayer d'autres superblocs de secours. Voici le début de la liste.
Superblocs de secours stockés sur les blocs :
32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208,
4096000, 7962624, 11239424, 20480000, 23887872, 71663616, 78675968, 10240000
On sait que le premier a déjà été fait sans succès
Si aucun ne donne de résultat, je ne vois pas trop l'intérêt d'en utiliser d'autres sauf si tu le demandes. Il faudra regarder testdisk voir photorec
On va quand même regarder si la trace dit quelque chose

Je ne suis pas un spécialiste de l'analyse des données SMART,
mais je trouve quand même qu'il y a beaucoup d'erreurs qui pourraient avoir été causées,
entre autres possibilités, par une alimentation ou/et une connectique défaillante.
Je laisse à ceux qui savent le soin d'interpréter ces retours.

Re : Raid 5 avec mdadm, superblock corrompu
Bonjour MicP.
Ces anomalies n'empêchent pas l'exécution d'un FSCK, tout au plus un ralentissement du fonctionnement.
Par exemple
Les Seek_Error_Rate sont respectivement 100, 076 et 077 alors que l'alerte est fixée à 045.
Les autres compteurs ne font pas l'objet de suivi d'alerte.
Hardware_ECC_Recovered Sont respectivement 100,100 et 082 alors que le seuil est fixé à 000.

Re : Raid 5 avec mdadm, superblock corrompu
Bonjour geole
Sur tous les disques que j'ai eu, la valeur brute de l'attribut 195 est toujours restée à zéro.
Mais j'ai parcouru plusieurs posts concernant l'attribut 195 de disques ST4000DM004
et on retrouve aussi cette augmentation rapide de la valeur RAW de l'attribut 195.
Donc, c'est peut-être un comportement "normal" pour ce type de disque.

Re : Raid 5 avec mdadm, superblock corrompu
Merci pour toutes ces informations.
J'ai en amont de mon NAS un onduleur afin d'éviter les coupures. Le NAS n'est pas allumé en permanence par contre.
J'ai tenté les commandes proposées mais sans succès donc je suis en train d'utiliser Photorec, je récupère une partie des données actuellement. Je fais passer plusieurs fois le script et un script maison de tri qui copie tout sur un cloud actuellement. J'espère récupérer une bonne partie tout de même. J'avais déjà tenté avec foremost il y a quelques semaines mais sans grand succès, beaucoup de fichiers étaient corrompus. Avec photorec c'est pas mal la !
Merci à vous encore !
