How to setup Azure Container Storage pool using pre-provisioned azure managed disks?

Roman Skolin (Admin) 0

I enabled Azure Container Storage in my cluster a couple of days ago using the azureDisks type. The default Azure Container Storage pool was configured and mapped to dynamically provisioned disks.

Now, I am trying to create a pre-provisioned storage pool using existing Azure-managed disks, following the official documentation: Create a pre-provisioned storage pool.

My AKS cluster has all the necessary roles to access my disks (Microsoft.Compute/disks/read).

After applying the given configuration from the documentation:

yaml Copy Edit apiVersion: containerstorage.azure.com/v1 kind: StoragePool metadata: name: sp-preprovisioned namespace: acstor spec: poolType: azureDisk: disks: - reference: /subscriptions/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx/resourceGroups/RG-QDRANT/providers/Microsoft.Compute/disks/disk0 - reference: /subscriptions/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx/resourceGroups/RG-QDRANT/providers/Microsoft.Compute/disks/disk1 the new storage pool is created, but the rest of the setup (PV, PVC, and StorageClass) is not properly created. In AKS, I can see my new storage pool, but it has 0 capacity and an "Unknown" status.

I tried reinstalling the Container Storage extension in AKS, but that did not help.

Is there anything else I need to do to create a new storage pool from existing disks in my Azure subscription?

Hi Roman Skolin (Admin),

Welcome to the Microsoft Q&A Platform! Thank you for asking your question here.

•\t Check Disk Status: Confirm the managed disks you are working with are unattached, healthy, and properly formatted. They must be empty and not have any file systems on them.

•\t Verify Permissions: Ensure that your AKS cluster's managed identity has the Microsoft.Compute/disks/read permission for disks in your Azure subscription.

•\t Update Storage Pool YAML: Have your YAML file properly reference each disk's full path and be sure it is correct. A revised example looks like this

apiVersion: containerstorage.azure.com/v1 kind: Storage Pool metadata: name: sp-preprovisioned namespace: acstor spec: poolType: azureDisk disks: - reference: "/subscriptions/{subscription_id}/resource Groups/{resource_group_name}/providers/Microsoft.Compute/disks/{disk_name1}" - reference: "/subscriptions/{subscription_id}/resourceGroups/{resource_group_name}/providers/Microsoft.Compute/disks/{disk_name2}"

• Create PV, PVC, and Storage Class: After ensuring the pool is created successfully with the correct capacity, create the PV, PVC, and Storage Class as outlined in your cluster configuration.

• Re-create Pool if Necessary: If the problem still exists, remove the storage pool and re-create it after verifying the above steps.

kubectl logs -n acstor <container-storage-controller-pod-name>

Recreate Pool if Needed: If the issue persists, delete the storage pool and recreate it after checking the above steps.

These actions should resolve the "Unknown" status and enable proper integration of the pre-provisioned disks into your Azure Container Storage environment.
