Unplug IPMI network cable - whistle was slow to get this alert, should not take > ~30 minutes to notify that a host is down

Power off host - we eventually received alerts on the OpenStack host but the K8 cluster was much quicker to notify to the issue. This would have been a problem if the host was not running k8 as well.

Disk fill on host - we filled up the root volume on the host, because neutron services never stopped the host still showed as connected however it was unusable. pf9-muster died, and the VMs on the host went into a paused state. Again the only reason we got an alert is that the k8 cluster died. This would not have worked if there was no k8.
