Astra Trident for Kubernetes and Openshift

Issue

When adding an application with pods to the Kubernetes or Openshift cluster, using Trident PVs, the PVs, PVCs and PODs are delayed for a long time before coming up.
Messages seen are:

Unable to attach or mount volumes: unmounted volumes=[PV_NAME], unattached volumes=[PV_NAME_2 PV_NAME PV_NAME_3 ...]: timed out waiting for the condition
AttachVolume.Attach failed for volume "pvc-UUID" : rpc error: code = DeadlineExceeded desc = context deadline exceeded
 

Additional errors from Trident give more context:

  • Trident logs show errors on volume creation and deletion:

backend cannot satisfy create request for volume trident_<PREFIX>_pvc_<UUID>: (ONTAP-NAS pool <AGGR>/<AGGR>; error creating volume trident_<PREFIX>_pvc_<UUID>: API status: failed,Reason: Failed to create the volume on node \"<STORAGE_NODE>\".Reason: Failed to store NVE key with key ID\"00000000000000000200000000000HEX-UUID0000000000000000\" on external key server \"<HOST_FQDN>:50100\
