Had a discussion today in the office where a quota based on physical capacity used by a SCM would be a good solution.
The surcease for this is mainly the use of containers and trident.
These admins don’t query and don’t care about space as they are not used to it. If you have mixed workloads on your ONTAP and mixed trident target on the same aggregate with other workloads they can easily fill the aggregate very fast. This would have a major impact on all other workloads running on that aggregate.
Today you need to have an own aggregate for trident to avoid this. Which more or less removes the benefit from an ONTAP system…
#Quota on SVM level

You can restrict SVMs to certain aggregates. Not ideal but I don't know if there's a way to segment that.

There is also an option to restrict max size of a request and another to limit (restrict) provisioning if the aggregate use% is above a certain level, if that could help mitigate until a better solution is ready.
Speaking of which, this is a well known thing and it is being worked on but the how, if and when is something for a private session with your local NetApp reps. 🙂

Many thanks for your replies. The dedicated aggregate isn’t a solution tbh as it is too static and removes the benefit of a shared storage.
The aggregate % thing is a way to mitigate it for the moment. I didn’t know this option. Regarding the rest we‘ll get in touch with our PTL. Thanks a lot!

A slight tangent on the primary ask - but @stable needle does it help if you could know when and which PVs, supporting which Namespace or Workload in a K8s cluster are driving overall capacity use? As an example, if you could be alerted or just see that 'Workload A' has contributed a load of growth on a set of volumesI ask because this is a thing which is available in Cloud Insights which *might *help in your situation. I realize this doesn't mean 'halt all growth past X on an SVM where PVs are consuming space'.

Hi @potent ravine this doesn’t help as we‘d like to limit the available capacity for the consumer
