Unable to drain longhorn nodes

I’m trying to take a node down for maintenance. Draining it shows this error:

cannot delete Pods with local storage (use --delete-local-data to override): cattle-prometheus/grafana-cluster-monitoring-65cbc8749-vdqf7, cattle-prometheus/prometheus-cluster-monitoring-0 cannot delete Pods not managed by ReplicationController, ReplicaSet, Job, DaemonSet or StatefulSet (use --force to override): longhorn-system/instance-manager-e-22a7ecfc, longhorn-system/instance-manager-r-24e06223

I’m not sure what to do here. “Forcing” seems bad, as there could be data loss.

Same problem for me.

I am also having this issue. I get this even when I use --force.
