    j'en compte 5 pourtant pas 6 :unsure:

    bon, alors, on va supposer qu'il prend le missing pour un disk

    donc, si il aime pas, on passe a 4

    mdadm --create /dev/md3 --verbose --level=5 --raid-devices=4 /dev/sda6 /dev/sdb6 /dev/sdd6 /dev/sde6 missing /dev/sdc6

    si quelqu'un a une bonne iddée, suis aussi preneur :P

    On dirait que le mot clé missing n'est pas reconnu. Ça va être dur aujourd'hui, mais v essayer de reproduire cela en virtualisation. Ainsi, je teste toute les commande les une a la suite des autres

    J'ai eu une petite heure pour reproduire le problème et cela donne ceci :

    Si le disque 4 contient bien les données, ca va fonctionner

    Voici la commande :

    mdadm --create /dev/md3 --verbose --level=5 --raid-devices=5 /dev/sd[a,b,d,e]6 missing

    après tu confirma la creation et après, si tout va bien :

    cat / proc/mdstat

    tu devrait voir ton raid md3 avec 4 disque sur 5

    après :

    pvs
pvdisplay
vgdisplay

    et ensuite on voit, mais normalement un reboot et c'est ok

    coté positif, en avance

    j'ai encore des iddée :

    l'endroit du disque manquant (missing) a une importante normalement :

    et le raid c'est monté avec des metedata 1.2 au lieu de 1.1

    tu peux essayer ceci :

    mdadm --stop /dev/md3

mdadm --create /dev/md3 --verbose --level=5 --raid-devices=5 --metadata=1.1 /dev/sd[a,b]6 missing /dev/sd[d,e]6

    le reste des commande est identique ;)
