Applies to

  • NetApp Astra Trident for Kubernetes (ontap-nas-economy driver, version 25.10.0)
  • Grafana Tempo application
  • Kubernetes (vSphere environment)

Issue

  • Grafana Tempo application logs report missing files when using Trident-provisioned NFS Persistent Volumes (PVCs).
  • Error messages observed:

  • The directories exist, but the files do not.
  • Errors only occur with Trident NFS PVCs; the issue does not appear when using vSphere CSI-provisioned VMDK volumes (local storage)
  • Other applications using Trident PVCs do not exhibit this problem
