Bonjour à tous,
Version courte :
Mon KS (ks380507) a eu des erreurs I/O sur le disque, des secteurs en attente d'être réalloués, et après formatage complet (pour finaliser la réallocation) finalement plus rien... Je ne fais plus confiance à ce disque, cependant il m'est difficile de prouver que celui-ci a des problèmes, mis à part l'historique des erreurs SMART. Est-il possible d'en changer quand même ?
Version longue (avec les détails) :
Mon KS a eu de gros soucis de disque dur il y a quelques jours, erreurs I/O, machine bloquée, obligé de rebooter, en rescue pour voir ce qui se passe. SMART indiquait Reallocated_Sector_Ct 0 mais Current_Pending_Sector 1. J'ai donc monté et transféré toutes mes données sur d'autres machines (avec des erreurs de lecture en prime, voir plus bas) et entrepris d'écrire des zéros sur tout le disque afin de réallouer ce secteur définitivement et ensuite faire changer le disque. Problème, à la fin du formatage, le secteur défectueux a disparu : Reallocated_Sector_Ct 0 et Current_Pending_Sector 0 ! Il ne me reste plus que quelques logs et quelques erreurs SMART pour prouver ma bonne foi :

Est-ce suffisant pour demander un remplacement de disque ? Je suis en train de le formater à nouveau avec /dev/urandom cette fois-ci afin de voir si il réagit différemment avec des données aléatoires mais j'en doute... mais je n'ai pas envie de tout rebasculer sur ce disque maintenant qu'il m'a fait un coup comme ça.
Merci d'avance !
Yann
