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.
