one solution is restart kubelet in the original node and also the node with azure disk (`sudo systemctl restart kubelet`), and then after a few minutes, check the pod & volume status.
- PV & PVC accessModes
accessModes do not enforce access right, but rather act as labels to match a PV to a PVC. One PV could only be bound to one PVC, and one PVC (after bound to a PV) could be used by multiple pods
Redhat Openshift provides a good example for you to understand.
Different Access modes for mounted volume in init container and actual container
- PVC readOnly setting
At present, we allow two approaches to set PVC's ReadOnly attribute: specified by Pod.Spec.Volumes.PersistentVolumeClaim.ReadOnly, or specified by PersistentVolume.Spec.<PersistentVolumeSource>.ReadOnly, but when we try to get the ReadOnly attribute from volume.Spec for a PVC volume, we only consider volume.Spec.ReadOnly, which only comes from Pod.Spec.Volumes.PersistentVolumeClaim.ReadOnly, see AWS as an example.
details:
-
CSI: readOnly field is not passed to CSI NodePublish RPC call
-
namespace can not be deleted
Try the following steps:
- Get all the resources in the namespace and delete if they’re some resources:
kubectl api-resources --verbs=list --namespaced -o name | xargs -n 1 kubectl get --show-kind --ignore-not-found -n $NAMESPACE
- Delete finalizers:
kubectl get namespaces $NAMESPACE -o json | jq '.spec.finalizers=[]' > /tmp/ns.json
kubectl proxy &
curl -k -H "Content-Type: application/json" -X PUT --data-binary @/tmp/ns.json http://127.0.0.1:8001/api/v1/namespaces/$NAMESPACE/finalize
