Périphérique: / dev / sda [SAT], 1 secteurs actuellement illisibles (en attente)
J'ai une matrice logicielle RAID 1 sur RHEL. Je reçois cette erreur par e-mail chaque matin: Périphérique:/dev/sda [SAT], 1 secteurs actuellement illisibles (en attente)
Lorsque je lance un test sur sda (ou sdb), tout semble passer. Suis-je en train de manquer quelque chose?
mdstat montre que la matrice RAID est correcte:
# cat /proc/mdstat

Selective self-test flags (0x0):
After scanning selected spans, do NOT read-scan remainder of disk.
If Selective self-test is pending on power-up, resume after 0 minute delay.
Votre SMART secteur en attente actuel a la valeur 1. Cela signifie qu'il y a un secteur défectueux sur le disque et que le micrologiciel du lecteur n'est pas en mesure de le réallouer, mais vous n'avez toujours aucun secteur réalloué, donc il est probable récupérable même si votre lecteur fonctionne depuis 5 ans dans un environnement peu sain - les températures peuvent atteindre 72 ° C.
Vous pouvez essayer de trouver ce mauvais secteur avec dd if=/dev/sda of=/dev/null et vous devrez ensuite remapper ce secteur en le remplaçant.
