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.
