Hi @rajans ,

For the iscsi non deleting PVC we will need more details from the logs.

You can get them with :

kubectl get pod -n unity | awk '/unity/ {system("kubectl logs --prefix=true --all-containers -n unity "$1" > /tmp/"$1".log")}'

That's an interesting use case on the NFS you can reach me in PM and share your email address.

For PS assistance same, please send me a PM message.

so upon pvc deletion it deletes from the openshift but not from the Unity .
