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

Thanks & Best Regards

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?
