RHOSP 13 Multiple Cinder Backend

Latest response

Hello Everyone

I want to ask all of you, maybe you have experience related my problems.

I already have a rhosp 13 cluster with cinder-volume and cinder-backup using NFS backend. it runs well without obstacles.

I want to integrate existing redhat ceph 3 with glance cinder and nova service on my cluster.
The following additional configuration configuration in the deployment script:
time openstack overcloud deploy --templates \

The problem is that in the Cinder configuration there is no addition of the rbd / tripleo_ceph variable, and in the service volume it also does not exist.

Can you tell me a proper and correct way to integrate cinder using ceph and nfs backend?

thank you
