--- features: - Add support for the tooz library. - Allow configuration of file/distributed locking for the share manager service. upgrade: - New options are necessary in manila.conf to specify the coordination back-end URL (for example, a Distributed Locking Manager (DLM) back-end or a file based lock location). The configuration determines the tooz driver invoked for the locking/coordination. fixes: - Share replication workflows are coordinated by the share-manager service with the help of the tooz library instead of oslo_concurrency. This allows for deployers to configure Distributed Locking Management if multiple manila-share services are run across different nodes.
