The NetApp driver has been working with FlexVol ONTAP volumes. The driver does not support scaling FlexVol volumes higher than 100 TiB, which was a theoretical limit for the large namespace that these containers were meant to handle. ONTAP's Flexgroup volumes eliminate such limitations. So, added the support for provisioning share as FlexGroup in the NetApp driver. The FlexGroup provision is enabled by new option `netapp_enable_flexgroup`, which will make the driver report a single pool represeting all aggregates. The selection on which aggregates the FlexGroup share will reside is up to ONTAP. If the administrator desires to control that selection through Manila scheduler, it must inform the set of aggregates that formss FlexGroup pool in the new option `netapp_flexgroup_pool`. Each NetApp pool will report now the capability: `netapp_flexgroup` informing which type the pool is. The following operations are allowed with FlexGroup shares (DHSS True/False and NFS/CIFS): - Create/Delete share; - Shrink/Extend share; - Create/Delete snapshot; - Revert to snapshot; - Manage/Unmanage snapshots; - Create from snapshot; - Replication[1] - Manage/Unmanage shares; The backend with one FlexGroup pool configured will drop the consistent snapshot support for all pools. The driver FlexGroup support requires ONTAP version 9.8 or greater. [1] FlexGroup is limited to one single replica for ONTAP version lower than 9.9.1.

Manila Development Docs
Files under this directory tree are used for generating the documentation for the manila source code.
Developer documentation is built to: https://docs.openstack.org/manila/latest/
Tools
- Sphinx
-
The Python Sphinx package is used to generate the documentation output. Information on Sphinx, including formatting information for RST source files, can be found in the Sphinx online documentation.
- Graphviz
-
Some of the diagrams are generated using the
dotlanguage from Graphviz. See the Graphviz documentation for Graphviz and dot language usage information.
Building Documentation
Doc builds are performed using tox with the docs
