Dear All:

I deploy a k8s cluster with 1 master and 1 worker. I've done all installation requirement from the installation guide as below. When I try to test the sample.yaml from csi driver package, everything does now work correctly

https://dell.github.io/csm-docs/docs/csidriver/installation/helm/unity/

Here is the environment info:

K8s version: 1.22.0

CSI Driver version: 2.22.0

The output related to sample.yaml

[root@k8s-master-1 ~]# kubectl get all -n test-unity
NAME READY STATUS RESTARTS AGE
pod/unitytest-0 0/1 Pending 0 45m

NAME READY AGE
statefulset.apps/unitytest 0/1 45m

[root@k8s-master-1 ~]# kubectl get pvc -n test-unity
NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGE
pvol1 Pending unity-virt2212drzmzg-iscsi 46m
pvol2 Pending unity-virt2212drzmzg-nfs 46m

I only test iSCSI and NFS, so only 2 pvc were list

PVC create were stock in pending state, waiting for volume create....

No PV were created

[root@k8s-master-1 ~]# kubectl get pv
No resources found

The controller driver log is as below

I found 10.96.0.1 was Kubernetes cluster IP, but why the controller show all this message.

Does anyone can help me to find out the problem?

Best Regards,
