Container qui ne démarre pas - Wiki Les geekeries de rungis

Dernière mise à jour : 04/07/2021 à 00h10

Probablement dû à la mise à jour du système proxmox, je me suis retrouvé avec un container sous debian 10 qui ne démarrait plus.
Voici les logs obtenus via la commande :

Code BASH :

 
lxc-start -n 103 -F -l DEBUG -o /tmp/lxc-103.log

103 est l'ID du container

Code BASH :

Après quelques recherches, l’enchaînement de commandes suivant m'a permis de résoudre le problème

Code BASH :

 
pct mount 103

Code BASH :

 
touch /var/lib/lxc/103/rootfs/etc/.pve-ignore.resolv.conf

Code BASH :

 
pct unmount 103

Code BASH :

 
pct start 103
