I'm not sure what's gone wrong but I have a volume that can't attach anywhere, my logs are showing the following despite the UI saying it's detached:

E1024 14:49:44.621450       1 volume_controller.go:216] fail to sync longhorn-system/pvc-336ed0a5-1889-4e0a-be69-e9cd6602b4af: fail to reconcile volume state for pvc-336ed0a5-1889-4e0a-be69-e9cd6602b4af: volume pvc-336ed0a5-1889-4e0a-be69-e9cd6602b4af has already attached to node kube-w-04, but asked to attach to node kube-w-03

How can I tell it that it's not attached to w-04?

This is a known issue. Please do: 1. Scale down the workload that is using this volume 2.

kubectl edit <http://volumes.longhorn.io|volumes.longhorn.io> pvc-336ed0a5-1889-4e0a-be69-e9cd6602b4af

and set the

spec.NodeID

to

""

3. Wait for volume to be detached in Longhorn UI 4. Scale up the workload
