alors j’ai pris le dernier installateur et refait une install se que je peut te dire dans l’immédiat :

Le plus inquiétant étant çà :
[code]mdadm --examine /dev/md0
mdadm: No md superblock detected on /dev/md0.
mdadm --examine /dev/md1
mdadm: No md superblock detected on /dev/md1.

Pb matériel des dd ?
hum peut etre une piste sur le liens que tu donne plus haut cela renvoie vers cette page :
raid.wiki.kernel.org/index.php/Superblock
si je comprend bien le noyau se base sur la version 0.90 de superblocks.
Alors que mdadm se base sur la version 1.2 d’où mon pb pour démarrer mon raid visiblement non ?
