Error: only dynamically provisioned pvc can be resized and the storageclass that provisions the pvc must support resize

Products

• VMware Telco Cloud Automation

Issue/Introduction

• Attempting to resize a PVC fails with the message:
  
  forbidden: only dynamically provisioned pvc can be resized and the storageclass that provisions the pvc must support resize
 
• The cluster was deployed through versions of TCA prior to 3.2
• The vsphere-csi cluster addon was removed and re-installed, and the default configuration was accepted.

Environment

3.2

Cause

Previous versions of TCA used the default storageclass name of 'vsphere-sc'. The default name is now 'vsphere-csi'.

By removing and re-installing the addons, unless the default name of the storageclass is changed, the new storageclass will have the name 'vsphere-csi'.

Existing PVCs will still be referencing the previous storageclass, which was removed with the addon.

Resolution

• Remove and re-install the vsphere-csi addon, updating the storage class name to the expected name, or
• Create a new storageclass

1. 1. SSH to the affected cluster
   2. Output the configuration of the existing storageclass to yaml
      • kubectl get sc <NAME> -o yaml > <FILENAME>
   3. Edit the 'name' field in the output file to match what is expected
   4. Apply the new configuration
      • kubectl apply -f <FILENAME>
   5. Retry the resize operation
