Applies to

  • Trident for Kubernetes/Openshift up to 23.01
  • ONTAP 9.7 to 9.7P13, ONTAP 9.8 to 9.8P11
  • Openshift 4.8.5
  • Kubernetes 1.21

Issue

When creating a number of ONTAP-driver PVCs for a new pod deployment, Trident has to create these on the ONTAP storage cluster, which takes time.
Depending on the number of PVCs requested at once, this runs into a timeout for the pod/application startup, failing the deployment, or leave a pod stuck in ContainerCreating for a while.
