Kubernetes: Can't delete PersistentVolumeClaim (pvc)

Question

I created the following persistent volume by calling

kubectl create -f nameOfTheFileContainingTheFollowingContent.yaml

apiVersion: v1
ki         


        

Answer 1

For me pv was in retain state, hence doing the above steps did not work.

1st we need to change policy state as below :

kubectl patch pv PV_NAME -p '{"spec":{"persistentVolumeReclaimPolicy":"Delete"}}'

Then delete pvc as below.

kubectl get pvc

kubectl delete pvc PVC_NAME

finally, delete pv with

kubectl delete pv PV_NAME

Answer 2

This happens when persistent volume is protected. You should be able to cross verify this:

Command:

kubectl describe pvc PVC_NAME | grep Finalizers

Output:

Finalizers: [kubernetes.io/pvc-protection]

You can fix this by setting finalizers to null using kubectl patch:

kubectl patch pvc PVC_NAME -p '{"metadata":{"finalizers": []}}' --type=merge

Ref; Storage Object in Use Protection

Answer 3

Just met this issue hours ago.

I deleted deployments that used this references and the PV/PVCs are automatically terminated.

Answer 4

In my case, as long as I delete the pod associated to both pv and pvc, the pv and pvc in terminating status are gone

Answer 5

I'm not sure why this happened, but after deleting the finalizers of the pv and the pvc via the kubernetes dashboard, both were deleted. This happened again after repeating the steps I described in my question. Seems like a bug.

Answer 6

You can get rid of editing your pvc! Remove pvc protection.

1. kubectl edit pvc YOUR_PVC -n NAME_SPACE
2. Manually edit and put # before this line
3. All pv and pvc will be deleted
