Hi All Good Day >From documentation we are able to understand that we can configure multiple backends for cinder (Ceph ,External Storage device or NFS etc) Is there any way we can choose the backend while instance launching .Say instance1 backend should be from an external storage device like EMC and instance2 to launch and have backend volume from ceph .Can this be achieved using cinder availability zone implementation or any other way? I have gone through below link (*section Configure Block Storage scheduler multi back end)* https://docs.openstack.org/cinder/latest/admin/blockstorage-multi-backend.html Suggestions please ..
