Bonjour,
La résolution de ce problème fait appel à votre expérience en :
Software: Linux / Raid-1 / mdadm / dmesg / (s)fdisk
Hardware: SATA / Dell PowerEdge 300
Notre petit serveur à tout faire est un rack Dell avec deux disque de 750Go en SATA monté en Raid-1 (mirror)
Le sdb avait commencé à manifester des crasses et s'est fait kické du Raid.
J'ai rebooté (!), re-fdiské/reformaté/rajouté au Raid, et hop le looOOoong crunch avait commencé. Il n'était pas arrivé au bout.
J'ai alors changé le drive.
Puis un autre.
Puis un autre.
4x.
Déjà .
(bon ok les deux premiers n'étaient pas neuf, mais en 2011, un disque peut survivre à 2000h de vols non?)
Bref, je commence à ne plus douter du drive...mais de l'interface sdb (et cela me fait très mal, je suis électronicien)

Je deviens un peu à court de tests/idées/disques neufs....
Les données, c'est pas trop grave, il y a un rsnapshot hourly.
Le downtime serait plus embêtant, et surtout, j'ai l'impression que le re-crunchage du Raid-1 est long et éprouvant pour le sda qui pourrait aussi un jour me dire flûte...
Vous pensez à quelque chose?
La résolution de ce problème fait appel à votre expérience en :
Software: Linux / Raid-1 / mdadm / dmesg / (s)fdisk
Hardware: SATA / Dell PowerEdge 300
Notre petit serveur à tout faire est un rack Dell avec deux disque de 750Go en SATA monté en Raid-1 (mirror)
Le sdb avait commencé à manifester des crasses et s'est fait kické du Raid.
J'ai rebooté (!), re-fdiské/reformaté/rajouté au Raid, et hop le looOOoong crunch avait commencé. Il n'était pas arrivé au bout.
J'ai alors changé le drive.
Puis un autre.
Puis un autre.
4x.
Déjà .
(bon ok les deux premiers n'étaient pas neuf, mais en 2011, un disque peut survivre à 2000h de vols non?)
Bref, je commence à ne plus douter du drive...mais de l'interface sdb (et cela me fait très mal, je suis électronicien)

Je deviens un peu à court de tests/idées/disques neufs....
Les données, c'est pas trop grave, il y a un rsnapshot hourly.
Le downtime serait plus embêtant, et surtout, j'ai l'impression que le re-crunchage du Raid-1 est long et éprouvant pour le sda qui pourrait aussi un jour me dire flûte...
Vous pensez à quelque chose?
