Demander au noyau d'ignorer un périphérique

[ziouplaboum]

[quote=“piratebab”]Le disque dur a subi une extinction sale (fin de batterie, pas de mise en veille) donc ça pourrait être une erreur physique?
si ton disque est compatible SMART, tu peux récupérer pas mal d’info sur sa santé avec smartmontools

Pas de support SMART sur ce périphérique:

tu n’avais pas attiré notre attention sur le fait que c’était un SSD!
Difficile de parler de dommage physique sur ce type de matériel.

[ziouplaboum]

L’idée de Pascal qui marchera si c’est une erreur localisée du media consiste à éliminer un accès à la zone douteuse: Si le premier secteur est bon, tu fais une table où la première partition commence à partir du du bloc numéro 20000 par exemple (adapte). Dans ce cas le noyau n’accède pas aux blocs pourris. Mais pour un SSD, j’ai du mal à y croire…

Ayé, ça semble être réglé! J’ai donc crée une partition de peu de blocs au milieu du disque, et y a plus de soucis dans dmesg, de plus je peux monter la partition. Qui sait, peut être pourrais-je même réutiliser le SSD en question?!

la partition:

Bon, mea culpa, piratebab a lu trop vite mais moi j’ai été optimiste un peu trop vite aussi… Les messages sont toujours présents au BOOT, voir plus bas.
Sinon, j’ai testé l’option quiet de SebP ça marche pas.

des infos sur les bad blocks.
storagesearch.com/bad-blocks-in-ssds.html

Je pensai que c’était géré par le contrôleur du SSD, mais il semblerai qu’au déla d’une certaine limite, il ne gère plus.
As tu essayé un format de fichier plus spécifique, tel que btrfs ?
Une piste ici:
storagesearch.com/bad-blocks-in-ssds.html

Je regarde ça de prêt car je viens de recevoir mon premier SSD, et avant de l’installer dans ma mythbox, je me renseigne …

[PascalHambourg]

L’option ‘quiet’ ne supprime pas l’affichage des messages d’erreur, seulement celui des messages d’information normaux.

tu n’avais pas attiré notre attention sur le fait que c’était un SSD! Difficile de parler de dommage physique sur ce type de matériel.

Pour quelle raison ? La mémoire flash est tout aussi sujette aux défauts que les mémoires de masse magnétiques.

[quote=“ziouplaboum”]Pas de support SMART sur ce périphérique:

Essaie quand même d’exécuter smartctl en ajoutant cette option ‘-T permissive’. J’ai constaté qu’elle était nécessaire avec certains disques un peu anciens. Essaie aussi d’activer SMART sur le disque avec l’option ‘-s on’ au cas où il serait désactivé.

Je ne comprends vraiment pas pourquoi le noyau continue à vouloir lire le secteur 2048 alors qu’il n’y a plus de partition à cet endroit…
J’ai deux nouvelles suggestions :

• Effacer complètement le MBR et sa table de partition avec dd (attention ne pas se tromper de disque!)

• Essayer d’écrire dans le secteur 2048 en espérant que le contrôleur du SSD détectera qu’il est défectueux réallouera dans une zone saine

J’ai mis des groupes de 16 secteurs car apparemment les secteurs détectés comme défectueux par badblocks sont regroupés par 8 blocs de 1024 octets (taille de bloc par défaut), soit 16 secteurs de 512 octets, c’est peut-être une unité de base de ce SSD.

je tente un reboot

[ziouplaboum]

Alors, reboot effectué, extrait du dmesg, ça bronche toujours.
Je vais vérifier que c’est vraiment pas possible d’enlever ce fichu disque, ça me gonfle, faut ouvrir la bécane en entier, pas juste la petit trappe…

[EDIT] les 4go de SSD qui sont en /dev/sda sont soudés à la carte mère, pas moyen de s’en débarrasser donc! aaaaaaaargh!
