Bonjour,
j'ai besoin de votre aide 😢
j'ai un serveur dédié chez soyoustart qui suite à un incident chez ovh ne démarre plus, hier matin le serveur avait un débit très limité ( 20M/5M) apres reboot / ouverture de ticket / divers reboot vers 10h, il à été inacessible pendant 6-7h, ovh est intervenu, avec est de la ram, changement de cable réseau et intervention sur le switch, suite à ça, le serveur est accessible mais uniquement en rescue.
je me suis connecté dessus pour voir les logs ( var/log) mais rien de récent, les derniers remonte au reboot de 10h et plus rien après.
le serveur est partitionner de cette façon la :
Filesystem Size Used Avail Use% Mounted on
/dev/md2 20G 6.6G 12G 37% /
udev 10M 0 10M 0% /dev
/dev/md3 5.4T 4.9T 280G 95% /home
le /dev/md2 est le raid 1 système et le /dev/md3 qui est mon raid 0 pour la partie home.
quand j'attaque le serveur en rescue le raid 0 est inactif...
le fdisk l- donne ceci :

le md3 est en inactif, comment le réactiver sans tout casser? je débute en linux, j'ai passé des dizaines sur le forum à lire et comprendre mais la, le raid soft, j'ai un peu peur de tout péter...
Merci beaucoup 🙂
