Cause
Based on the Kube logs from when the service was last active, we can observe that it was failing to run the PMK stack scripts as it could not find the lsb_release utility.

xxxxxxxxxxpf9@test:~$ sudo systemctl restart pf9-hostagent- Post restart of the pf9-hostagent service, the pf9-nodeletd service should start back up along with the rest of the PMK stack, and the node will then be reported to be in a healthy state to the management plane.
