Re: raid10 changement de configuration ?
Bonjour,

Combien de disques y a t'il dans le serveur?
Il y a toujours les 5 disques

mdadm.conf est il toujours
bon ?
Oui les modifs effectuées sont toujours présentes.
Le renommage des disques ne se fait pas seul, un coup d'oeil dans
dmesg devrait apporter des informations
C'est sûrement ce que je me suis dit également, les disques semblent
changer de nommage au boot.
Voilà ce que me dit dmesg, je ne suis pas un expert, j'ai extrait les
lignes correspondant au montage des disques et du RAID.
Ce que je comprend c'est que les disques HGST sont connectés en SATA et
que les disques WD sont connectés en SCSI.
Le raid essaie de monter les disques et n'y arrive pas car les disques
SCSI ne sont pas encore montés ?
Vous comprenez ça comme moi ?

Pourquoi les disques changent de label ?
