Question

define storageClass that targets a specific ClusterStorage

Daniele Francioni 21

as per https://learn.microsoft.com/en-us/azure/azure-local/deploy/enable-external-storage?view=azloc-2606#step-10-add-storage-path-in-the-azure-portal, we have added a new Storage Path. Now we would like to provision persistent volumes from a local AKS Cluster in that storage path.
as per https://learn.microsoft.com/en-us/azure/azure-local/manage/use-external-storage-for-containerized-workloads?view=azloc-2604, it should be possibile to create a storage class that can be used to place PVs on a specific local path, still the documentation lacks of examples.

Where can I find an example to create a storageclass that uses c:\ClusterStorage\Volume1 (for example) to store PVs from the AKS cluster?

Hi ,

Thanks for reaching out to Microsoft Q&A.

You cannot directly point a Kubernetes StorageClass to a Windows path like C:\ClusterStorage\Volume1 in AKS (including azure Local/AKS on HCI). Kubernetes works through CSI drivers, not raw host paths. To use that Cluster Shared Volume, you must expose it via a supported CSI driver such as the SMB CSI driver or a host-based CSI (for ex, SMB share backed by that path). Practically, you first share C:\ClusterStorage\Volume1 as an SMB share from the host, then create a StorageClass referencing the SMB CSI driver with the share UNC path (for example \\node\share). The StorageClass does not take local disk paths; it only takes driver-specific parameters (server/share for SMB, export path for NFS, etc.). There is no official example mapping directly to C:\ClusterStorage\... because that is not a supported abstraction.
