Bonjour,

c'est un serveur qui dispose d'un IPMI/KVM ?

Cordialement, janus57

FAPM 2022-08-24 07:57:30 UTC #26

Bonjour,
Bien sur, à la demande ... le KVM IP est facturé 25,00€ HT la journée par OVH ...

janus57 2022-08-24 08:32:30 UTC #27

Bonjour,

Ah il fait encore partie de cette série de serveur...

Perso je ferais une VM en mode rescue qui va utiliser les 2 disques du serveur pour avoir une visualisation de la séquence de boot.

Exemple pour installer une ISO sans accès KVM/IPMI : https://www.emaxilde.net/posts/2021/07/25/installer-un-serveur-dedie-sans-acces-kvm-ou-ipmi.html

P.S. méthode déjà utilisée pour réparer un upgrade de PVE6 à PVE7 (Raid1 via ZFS) et une seconde fois après un changement de carte mère qui avez laissé le boot en erreur.

Cordialement, janus57

FAPM 2022-08-24 10:25:58 UTC #28

Merci beaucoup pour cette solution mais je ne digère les pratiques scandaleuses de OVH.

janus57 2022-08-24 10:39:54 UTC #29

Bonjour,

Perso je ne fait pas confiance à ce genre de solution, donc mes serveurs ont toujours boot sur leur disques comme ça ne je suis pas dépendant de OVH pour savoir si les serveurs vont reboot.

Cordialement, janus57

FAPM 2022-08-24 10:46:44 UTC #30

Vous résumez parfaitement ...
Ne jamais faire confiance à OVH ...
Travailler avec un fournisseur avec lequel "on ne sait jamais si son serveur va redémarrer" car ils ont pris l'initiative, "sans prévenir" et "sans accompagner" de supprimer une fonctionnalité mise en avant par eux même dans un temps précédent ... c'est tout simplement scandaleux.

On se rappelle tous de l'incendie du DC de OVH
OVH menacé d'une action collective suite à l'incendie de son data center

Made in OVH ... pitoyable.

FAPM 2022-08-24 11:06:00 UTC #31

@OVH :
Ayez le cran de publier publiquement le nombre de vos serveurs qui tournent encore sur le kernel OVH ...

Qui, n'oublions pas l'argument pitoyable du support OVH, je cite :

"le netboot kernel OVH était un mode de fonctionnement de tests, celui-ci permettait de rapidement tester un kernel géré par OVH.
Cependant, celui-ci n'est pas fait pour rester comme mode de démarrage principale.
Celui-ci est simplement pour diagnostique, le mode de démarrage normal est sur disque dur."

Fritz2cat 2022-08-24 15:54:23 UTC #32

Bonjour,

avez-vous un backup de ces répertoires et fichiers avant le plantage ?

/boot/
/etc/grub.d/
/etc/default/grub
/etc/default/grub.d

FAPM 2022-08-24 16:10:24 UTC #33

bonjour @Fritz2cat
Malheureusement non car ca remonte à + 1 an ...
C'est suite à un yum update ...
Pourtant, les images des kernel dispo dans /boot sont vieux ... 2021 ...
Je ne comprends pas :(

PS : j'insiste à trouver une solution car je sais très bien que d'autres seront confrontés à cette situation donc j'espère trouver une solution afin d'aider à mon tour ...

FAPM 2022-08-24 16:32:41 UTC #35

Vous êtes bien dans votre chroot, j'espère ?
Le grub du rescue ne nous intéresse pas.

Je n'ai pas de centos7 sous le coude, juste du debian en versions 10 et 11.

Dans un Debian 10: /etc/default/grub (uniquement les lignes qui ne sont pas en commentaires)

GRUB_DEFAULT=0
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="noquiet nosplash"
GRUB_CMDLINE_LINUX="rootdelay=10 rootdelay=10"
GRUB_DISABLE_LINUX_UUID="true"

Donc pour plus de sécurité, montez-vous une machine virtuelle CentOS7 chez vous et récupérez ces fichiers vitaux, adaptez les UUID si nécessaire, après je vous renvoie à "internet" sinon je vais dire des bêtises...

FAPM 2022-08-24 18:17:12 UTC #39

Oui, en chroot effectivement
