Bonjour à tous,

J'essaye depuis "quelques" jours de booter en raid 1 logiciel sur deux disques
durs Sata.
Voici le matos : carte mère Asus P5S800-VM, le chipset Sata SIS964.

Lors de l'install de Sarge, le kernel 2.4 (par défaut) reconnaît bien mes deux
DD Sata ; par contre le kernel 2.6 n'arrive pas à les détecter... J'ai
solutionné le PB en faisant mon install avec un 2.4 puis j'ai recompilé (via
kernel-package) un nouveau noyau 2.6.12.4 en y intégrant en interne les modules
Raid (md + raid1) et SATA (sata_sis ...). Pour configurer le raid et faire les
installations je me suis aidé de plusieurs docs, notamment celle-ci : <a
href="http://www.epimetrics.com/topics/one-page?page_id=421&amp;topic=Bit%2dhead%20Stuff&amp;page_topic_id=120";>RAID1
on Debian Sarge</a>.

J'arrive à créer mon raid (via mdadm --create /dev/md0 ...) mais lors du reboot
suivant, il ne les redétecte pas !

Je pense que cela vient du fait qu'il les recherche (via md autodetecting) alors
qu'il n'a pas finit de détecter les disques durs SATA. Peut-on changer l'ordre
des lancements des modules ? Ou est-ce une mauvaise configuration ? ...

Merci de votre aide,

François, qui va faire une pause :-(
