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?
