CSI driver for Unity 1.4 with Openshift 4.6
Host : Redhat 7.8 + openshift 4.6
Storage : UnityOS 5.0.3.0.5.014
CSI Driver for Unity Version : CSI Driver for Unity 1.4
Mount protocol : NFS ISCSI
When NFS PVC is created the export is mountable and read write only by root users
For non-rootusers to write should customer repermission like create a subfolder and permission so that non-root users can write .
Any knowns issues such as
When we delete PVC for ISCSI, it will not removed from Unity side
Pod does not get IP when PVC is created
sorry for posting my problem here
Are there any professional services that can implement the CSI for openshift for a customer who is a dark site , They cannot send us any logs
Are there any specific logs that can be collected to troubleshoot the issue .

The issue has been resolved
customer set the
https://docs.openshift.com/enterprise/3.0/architecture/additional_concepts/storage.html
persistentVolumeReclaimPolicy: Recycle to persistentVolumeReclaimPolicy: Retain
so upon pvc deletion it deletes from the openshift but not from the Unity .
apiVersion: v1
kind: PersistentVolume
metadata:
name: pv0003
spec:
capacity:
storage: 5Gi
accessModes:
- ReadWriteOnce
persistentVolumeReclaimPolicy: Recycle
nfs:
path: /tmp
server: 172.17.0.2

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.
