Hello. I just summary for who looking this information likes me My problem can be addressed via cinder active-active. It will work if a cinder driver supports it. This is an example for CEPH and Koll-Ansible as Openstack Deployment tool. /etc/kolla/config/cinder.conf [DEFAULT] cluster = ceph /etc/kolla/globals.yml enable_redis: "yes" https://opendev.org/openstack/kolla-ansible/commit/d72500c6ff6c378e044c381ed... cinder-manage update_host from @Tobias Urdin <tobias.urdin@binero.com> will be helpful if we change cinder-volume service to another host when we want to replace or change storage nodes.

Greeting,
Cinder-volume host-group may help you this case , all cinder-volume service will expose same service hostname instead of cinder node’s hostname, you should check reference best practice of tripleO deployment for cinder-volume e.g. https://access.redhat.com/solutions/3524681

Hello guys.
Every volume was managed by a specified host. When this host was down or removed. How Can I extend this volume which was managed by this host? I would like to know if we have a solution for this case?
