@derekbit Yes, I've confirmed after executing argocd app delete longhorn, only longhorn-manager and longhorn-ui pods are deleted, most of longhorn components like longhorn-instance-manager, engine-image and csi-component pods are still there, and longhorn crd are not deleted as well:

Do you have a clue about what's missing or what could cause this symptom?

@yangchiu Thanks for the quick update. What's the longhorn version? Can you send me the kubeconfig in our internal slack channel? I will check it later. Thank you.

After a quick check, I found argocd app delete longhorn directly deleted resources in longhorn-system namespace (codes). The deletion process doesn't execute longhorn-manager uninstall as the uninstallation process of helm.
Currently, the PreDelete is not supported in ArgoCD yet.
