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
