Bonjour, J’essaie sans succès d’effectuer des migrations de volumes attachés d’un backend LVM à un autre (tous les deux dans le même volume_type). J’obtiens systématiquement un message d’erreur dans les logs cinder-volume sur le noeud de storage me signalant un problème de endpoint. 2017-09-07 14:15:18.986 1031 INFO cinder.volume.flows.manager.create_volume [req-34f2d626-a9f0-4ed2-a6e3-819910b40178 7178992f9edf451f8904457fff664b36 c2507c3c11c544408f0486b3efe475a0 -

Je ne pense pas avoir d’erreurs dans mes configuration étant donné que je peux sans problème créer des instances avec des volumes attachés, je peux également effectuer des migration live des instances entre différents nœuds compute (donc mes libvirtd sont bons). J’ai l’impression qu’il y a quelque chose de buggé qui empêche cinder de communiquer avec le endpoint de nova mais je ne trouve pas. Est-ce que quelqu’un pourrait m’aider sur ce problème ? Merci Hervé
