The Newly installed Trident operator can not identify the old PV/PVC with the old trident backend UUID

Applies to

• Trident
• Kubernetes

Issue

• Deployed with tridentctl on Kubernetes.
• The Newly installed Trident operator can not identify the old PV/PVC with the old trident backend UUID.
• After upgraded tridentctl failed, then delete all the trident pods manually.
• Then installing the Trident operator, so the trident backend UUID is changed.

Example:

./tridentctl -n trident get backend
