NetApp ONTAP driver: added support for FlexGroup pool using the NFS
|
|
mode. There are several considerations for using the driver with it:
|
|
|
|
1. The FlexGroup pool is only supported using ONTAP storage 9.8 or greater.
|
|
|
|
2. The FlexGroup pool has a different view of aggregate capabilites,
|
|
changing them by a list of elements, instead of a single element. They
|
|
are ``netapp_aggregate``, ``netapp_raid_type``, ``netapp_disk_type`` and
|
|
``netapp_hybrid_aggregate``. The ``netapp_aggregate_used_percent``
|
|
capability is an average of used percent of all FlexGroup's aggregates.
|
|
|
|
3. The ``utilization`` capability is not calculated to FlexGroup pools, it is
|
|
always set to default of 50.
|
|
|
|
4. The driver cannot support consistency group with volumes that are over
|
|
FlexGroup pools.
|
|
|
|
5. The driver cannot support multi-attach with volumes that are over
|
|
FlexGroup pools.
|
|
|
|
6. For volumes over the FlexGroup pool, the operations of clone volume,
|
|
create snapshot and create volume from an image are implemented as the NFS
|
|
generic driver. Hence, it does not rely on the ONTAP storage to perform
|
|
those operations.
|
|
|
|
7. A driver with FlexGroup pools has snapshot support disabled by default. To
|
|
enable, you must set ``nfs_snapshot_support`` to true in the backend's configuration
|
|
section of the cinder configuration file.
|
|
|
|
8. The driver image cache is not applied for volumes over FlexGroup pools.
|
|
It can use the core image cache for avoiding downloading twice, though.
|
|
|
|
9. Given that the FlexGroup pool may be on several cluster nodes, the QoS minimum
|
|
support is only enabled if all nodes support it.
