I might think this is related to the un-installation incomplete.
Did you refer to this doc: uninstalling-longhorn-using-kubectl to uninstall Longhorn?
Would you mind running this command to see if there are any remaining resources that weren't deleted? 
kubectl api-resources --verbs=list --namespaced -o name   | xargs -n 1 kubectl get --show-kind --ignore-not-found -n longhorn-system

Did you execute environment shell script? Is the iscsid process running smoothly on this node?
