Probleme construction RAID soft

Bonjour,

Après plusieurs tentatives je n'arrive pas à construire mon RAID Soft sur 3 disques 2To tout neuf.
Au départ j'ai essayé de construire un RAID 5 sur ces 3 disques et cela échouait à la fin de la synchro en me disant qu'un disk était défectueux.
J'ai alors mis le disque défectueux de coté et j'ai essayé de construire un RAID 1 sur les 2 disques restants. Même résultat : après la synchro il me dit qu'un disque est encore défectueux.

Ci-joint un extrait du fichier /var/log/messages :

Je n'arrive pas à comprendre la source réelle du problème :
- est ce matériel ? Disques défectueux ? Bizarre quand même les 3 sont
tout neufs !
- est ce un problème de configuration au niveau du Bios ? (Pour info j'utilise
ma carte mère est la : Asus M3N-HT Deluxe)
- est-ce un problème au niveau du driver Sata ? (OS = opensuse 11.3)

Sachant que la construction du RAID avec des disques de 2to est très longue (> 10 heures) je ne peux pas m'amuser à faire des tests chaque jour ... je compte donc sur votre aide :)

Merci d'avance pour les informations que vous pourriez me donner afin de réussir à construire mon RAID (1 ou 5).

Noki

Attention le raid soft y'a pleins de choses à regarder de près :

si ton bios gere du raid soft ou semi-soft (pour M$ qui comme d'habitude refuse tous standard) DESACTIVES dans les 2 cas bien sur....

et crées un raid sur les 3 disques si et seulement si / et /boot sont ailleurs. (4 disques donc !)

si tu n'as pas 4 disques mais bien 3*2T, utilises 2*2to pour un raid 1 soft.

si tu veux avoir 3*2To dont le / il te faut imperativement* une carte RAID hardware.






NOTA : *Imperativement ou presque car dans la pratique ca peut très bien fonctionner mais en théorie non par concequent il n'existe pas de garantie de stabilitée.



attention aussi à la taille adressable des disques
3*2to (raid 5) donne 6To ta machine peut elle adresser toute la surface ?
par exemple ext3 utilises des blocks de taille fixes qui permettent pas à une partition unique de dépasser les 2.2To
ou 4To avec une config spéciale (à créer à la main obligatoirement, pas à l'installation du système)



tu devrais lire ceci
http://http://www.cyberciti.biz/tips...eater-2tb.html

Merci pour ce retour frp31.

Cependant le lien que tu donnes ne fonctionne pas :cry:

Tu fais également allusion à des options du Bios pour la gestion du raid soft ou semi soft : aurais-tu des exemples d'option à me donner pour que je puisse vérifier ma config ?

En effet, peut être que la taille de mes partitions est en cause. Je vais donc faire des tests sur des partitions beaucoup plus petites.

Si tu as des infos à me donner sur la capacité maximale adressable d'un système Linux je suis preneur (pour info je suis sur opensuse, kernel 2.6, 64 bits).

Merci encore pour ton aide.

Bonjour,

J'ai enfin réussi à crééer mon RAID !! :)
Pour ceux que ça intéresse voici les actions qui m'ont permis d'y arriver :

- J'ai mis à jour le bios de ma carte mère
- Par précaution j'ai aussi changé les cables SATA qui reliaient mes disques à la carte mère
- J'ai recréé mes partitions en les alignant correctement

Résultat :
Je n'ai plus aucune erreur SATA dans mon fichier /var/log/messages.
J'ai de bonnes performances : 80Mo/s lors de la construction du Raid alors que j'étais à 20Mo/s dans mes tests précédent !!

Merci à frp31 pour son aide.
