.Shared File Systems support for scaleable CephFS-NFS
The Shared File Systems service (manila) now supports a scaleable CephFS-NFS service. In earlier releases of Red Hat OpenStack Platform, only active/passive high-availability that was orchestrated with Director, using Pacemaker/Corosync, was supported. With this release, deployers can create active/active clusters of CephFS-NFS and integrate these clusters with the Shared File Systems service for improved scalability and high availability for NFS workloads.

As TripleO moves from using ceph ansible to using cephadm as the deployment tool [0], Manila needs to follow by adapting how the drivers communicate with Ceph. For the upcoming cycle, TripleO aims to deploy NFS Ganesha using cephadm as well [0], and this has an impact on the ceph nfs driver. The driver needs to be adapted to start leveraging the nfs plugin for ceph mgr in order to provision shares to the end user.
