[Bug]: kadalu-csi-nodeplugin is not able to authenticate gluster fs server

@aravindavk do you remember what option has high priority? If not, will have a quick look at the code.

looks like kadalu_format: native (default value) is taking high preference here. Removing the default value for kadalu_format field from CRD file will fix this issue.

What am I missing here?

• mostly nomenclature I believe

• see if these terms make sense https://thoughtexpo.com/exploring-kadalu-storage-in-k3d-cluster-glusterfs/#terminologies

• gist would be, you are use external gluster, in native mode it'll be multiple PVs per gluster vol and in non-native mode it's 1 gvol : 1 pv

Change kadalu_format to single_pv_per_pool ---> In this fix, please remove default value given for kadalu_format field in CRD file.
https://github.com/kadalu/kadalu/blob/devel/helm/kadalu/charts/operator/crds/kadalu_storage.yaml#L45
Because if I just use single_pv_per_pool: true in my kadalu storage class, I still see storage class getting created with single_pv_per_pool as "False", as default value "native" is getting applied for kadalu_format field.

This is the file I applied.

apiVersion: kadalu-operator.storage/v1alpha1
kind: KadaluStorage
metadata:
  name: check-vol
spec:
  details:
    gluster_hosts: [10.10.126.140,10.10.136.24,10.10.146.207]
    gluster_options: log-level=DEBUG
    gluster_volname: glustervol3
  pvReclaimPolicy: retain
  single_pv_per_pool: true
  type: External

This is the object which got created.

allowVolumeExpansion: true
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  annotations:
    kubectl.kubernetes.io/last-applied-configuration: |
      {"allowVolumeExpansion":true,"apiVersion":"storage.k8s.io/v1","kind":"StorageClass","metadata":{"annotations":{},"name":"kadalu.check-vol"},"parameters":{"gluster_hosts":"10.10.126.140,10.10.136.24,10.10.146.207","gluster_options":"log-level=DEBUG","gluster_volname":"glustervol3","hostvol_type":"External","single_pv_per_pool":"False"},"provisioner":"kadalu"}
  creationTimestamp: "2023-04-12T08:05:59Z"
  name: kadalu.check-vol
  resourceVersion: "13874"
  uid: 80876066-2917-41fe-904f-db7d13058f6d
parameters:
  gluster_hosts: 10.10.126.140,10.10.136.24,10.10.146.207
  gluster_options: log-level=DEBUG
  gluster_volname: glustervol3
  hostvol_type: External
  single_pv_per_pool: "False"
provisioner: kadalu
reclaimPolicy: Delete
volumeBindingMode: Immediate

Now, I have to use both fields(kadalu_format: non-native single_pv_per_pool: true) in my storage yaml file to make this work.
