FAQ

Q: PVC status remains Pending? A: Check whether there is an available PV or dynamic StorageClass. If using a static PV, confirm that the PV's capacity, access mode, and reclaim policy match the PVC.

Q: Deleting a PV prompts that there is an associated PVC? A: First delete the PVC bound to that PV, or ensure the PVC has been Released and the reclaim policy is Retain/Delete before deleting the PV.

Q: Can StorageClass be modified online? A: Some fields of a StorageClass (e.g., parameters) can be modified via YAML editing, but core fields (e.g., provisioner) are typically not modifiable. Verify the impact before making changes.
