longhorn: [BUG] Error starting manager: upgrade Pods failed

Describe the bug I have have the following message when starting the manager pod on a second node on the cluster. All appears to be OK with the first node.

level=fatal msg="Error starting manager: upgrade Pods failed: upgrade from v1.0.2 to v1.1.0: upgrade volume failed: Operation cannot be fulfilled on volumes.longhorn.io \"pvc-6a457e39-109f-4b21-aa4f-9446c90e6539\": the object has been modified; please apply your changes to the latest version and try again"

What does this mean and how to solve this error?
