Freedos sous Proxmox

Dans un premier temps :

systemctl restart pvedaemon pveproxy

Si pas mieux :

pvecm expected 1
pvecm updatecerts
systemctl restart pvedaemon pveproxy
systemctl restart pve-cluster

Si jamais l'état des VM n'est pas visible :

systemctl restart pvestatd

Parce que je ne m'en rappelle jamais.

pct enter <id>

Si changement d'IP du serveur, le certificat auto-signé n'est pas identifié avec la bonne IP.

Modifier dans le Hosts (Datacenter > choisir la nœud > System > Hosts) où 192.168.1.200 est la nouvelle IP :

192.168.1.200 pve.test.lan pve

Renouveler le certificat puis redémarrage du serveur web :

pvecm updatecerts -f
systemctl restart pveproxy

vzdump -stop 
# si pas fonctionnel
ps -aux | grep vzdump
kill -9 PROCESS_ID
# si pas fonctionnel
umount -f /mnt/nfs/pointdemontage
qm unlock ID_VM
