Re : raid 5 : perte données après create... récupération possible ?

Les quatre disques sont en bon état. Je ne sais pas  pourquoi le raids n'a été automatiquement redécouvert.  Tu as certainement  oublié de booter après avoir rebranché les disques/installer mdadm
Si le raid avait été découvert, tu n'aurais pas pu faire la création car ressources occupées...

reboot pour être sûr puis :

kholo@monde:~$ ls /dev/md
md/    md127

Re : raid 5 : perte données après create... récupération possible ?

question naïve...
si mon create a écrasé les superblocs d'origine, y a t'il un moyen de restaurer un ou des backups ?

Re : raid 5 : perte données après create... récupération possible ?

j'ai pu réunir 5 disques de 500 Go...
j'en trouverai bien 4 de bon je pense...
ce soir, je copie mes disques...
je fais cela avec ddrescue...
je ne pense pas pouvoir me remettre dessus ce weekend mais je verrai à faire un point pour lundi...

Re : raid 5 : perte données après create... récupération possible ?

Bonjour
Si ton "create" a fait des dégâts, je ne connais que la solution de restaurer la totalité de chaque disque. Mais tu n'as pas de sauvegarde faite avant l'incident.

Les traces ne donnent pas d'explication complémentaire pour le message d'erreur.

On va tenter de regarder le contenu du premier bloc raids de chaque disque.

sudo dd if=/dev/sda count=1 bs=4096 2>/dev/null | hexdump -C
sudo dd if=/dev/sdb count=1 bs=4096 2>/dev/null | hexdump -C
sudo dd if=/dev/sdc count=1 bs=4096 2>/dev/null | hexdump -C
sudo dd if=/dev/sdd count=1 bs=4096 2>/dev/null | hexdump -C

Mais je suis incompétent pour déchiffrer ce qui sera produit. Alors, si tu pouvais faire aussi la même chose sur un autre raid5 resté opérationnel,  la comparaison pourrait aider.

Je pense que c'est le moment de contacter un professionnel de la réparation si tu ne te lances pas avec photorec. RMY est joignable  par messagerie https://forum.ubuntu-fr.org/profile.php?id=20551 et https://forum.ubuntu-fr.org/viewtopic.php?id=447877
