I messed up with uninstalling and now the namespace is stuck on "Terminating", I don't seem to have any stale resources left besides the namespace, which prevents me from installing it again 😕 What I initially did was attempting to uninstall just by deleting the namespace, unfortunately I only read the documentation about uninstalling after that, and it doesn't seem to help at this point.

$ kubectl get all -n longhorn-system
No resources found in longhorn-system namespace.

$ kubectl get namespace longhorn-system
NAME              STATUS        AGE
longhorn-system   Terminating   104m

should I just rebuild the cluster? 😢

The graceful way of uninstalling Longhorn system is to follow this doc: https://longhorn.io/docs/1.3.2/deploy/uninstall/
