Hi Vincent, Just to complement what Mike and Gorka said, Cinder NFS drivers does not provision FS services. It 'consumes' a FS export, and provisions block storage. To be more detailed, the Cinder NFS backend, mount a remote share from a NFS server, and create/stores the cinder volumes as files inside this exports on the volume node. In a scenario that you have Manila and Cinder, if Manila is using the generic driver and Cinder the NFS backend, before create a share, Manila will create a volume in Cinder, which will store that in the NFS share as a file.
