bonsoir
J'ai voulu profiter de la baisse de température pour offrir une
nouvelle machine à ma Debian (kit complet boîtier, carte mère RAM, un
don de mon employeur d'une machine décommissionnée pour absence de
support W11). Ma Debian est une version stable amd64
D'habitude, je prends le disque de l'ancienne machine, je le mets dans
la nouvelle, et pouf ça marche. Enfin ça démarre ; après faut mettre les
drivers à niveau, mais ce n'est pas le sujet
Seulement depuis que j'ai l'ancien boîtier j'ai migré mon système sous
RAID1, qui fonctionnait sans pb sur l'ancienne machine.
Là ça ne démarre pas, il bloque après Grub sur un message mdadm : "No
device listed in conf file where found" répété plusieurs fois
Puis Alert UUID-machin not found, dropping to a shell
donc busybox initramfs
J'ai booté sur systemrescuecd 12.01 où j'ai pu monter et vérifier les
partitions RAID.
Donc un changement de machine ne fait pas perdre le RAID.
un blkid m'informe que l'UUID de la partition "manquante" est /dev/md127
correspondant à /
Le BIOS me confirme avoir correctement détecté les deux disques du RAID.
Systemrescuecd aussi.
Je suis en legacy boot, systemrescuecd également, donc pas de pb de là.
Je manque d'idée, je suis preneur des vôtres.
Je vous joins à toute fin utile un blkid et la config mdadm :
