But when you use the custom backend method that Emilien pointed you to use, then you are responsible for supplying all the pieces for the backend(s) to function correctly. This means you will need to generate the nfs shares file on the host (controller), and then bind mount the file using CinderVolumeOptVolumes so that the shares file on the host is visible to the cinder-volume process running in a container.<br></div><div> <br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div>I'm wondering if it's possible to define a second backend by creating another service, for example "OS::TripleO::Services::CinderBackendNetApp2" ?</div></div></blockquote><div><br></div><div>Sorry, this won't work. TripleO will trying to deploy two completely separate instances of the cinder-volume service, but the two deployments will step all over each other.
