Hi Jean-Philippe, we had the same issue with ceph as backend. This fixed the problem in our setup: https://ask.openstack.org/en/question/87545/cinder-high-availability/
Although the above link talks about an active-active setup, the official docs mention the hostname in the configuration also for an active-passive setup: https://docs.openstack.org/ha-guide/storage-ha-block.html#configure-block-storage-api-service regards Christian Zunker Jean-Philippe Méthot <jp.met...@planethoster.info> schrieb am Fr., 6.
