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.

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, the configuration
|
|
option ``netapp_flexgroup_pools`` can be used to tune the storage pool
|
|
layout.
|
|
|
|
When enabling FlexGroup, the FlexVol pools continue enabled by default.
|
|
For having only FlexGroup, the new option ``netapp_flexgroup_pool_only``
|
|
must be set to `True`.
|
|
|
|
Now, each NetApp pool will report the capability: `netapp_flexgroup` informing
|
|
which type of share resides there (FlexGroup or FlexVol).
|
|
|
|
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;
|
|
- Manage/Unmanage shares;
|
|
|
|
FlexGroup feature requires ONTAP version 9.8 or newer.
|
|
Replication with more than one non-active replica per share requires
|
|
ONTAP 9.9.1 or newer.
