Issue

After installing Trident on the Kubernetes cluster, and setting up the StorageClass for an NFS PV, for example for NFS/NAS usage:
  • provisioner: csi.trident.netapp.io
  • backendType: "ontap-nas"
  • storagePools: "nasvol:.*"
  • (other options)

the POD creation fails, and trident is not provisioning a volume:

#kubectl get pvc -A
NAMESPACE  NAME                                STATUS  VOLUME CAPACITY ACCESS NODES STORAGECLASS AGE
monitoring proemetheus-k8s-db-prometheus-k8s-0 Pending                              <SC_NAME>
monitoring proemetheus-k8s-db-prometheus-k8s-1 Pending                              <SC_NAME>

 
The error message shows:
msg="GRPCerror: rpc error: code = InvalidArgument desc = no available storage for access modes: [ReadWriteOnce]" logLayer=csi_frontend requestID=<REQUEST-UUID> requestSource=CSI
