Hi, Last night we have an incident of a failed host. Engine issued a fence but did not restart the vms running on that node on other operational hosts. I'd like to know if this is normal or I can tune it somehow.
Here are some relevant logs from engine: 2018-09-05 03:00:51,496+03 WARN [org.ovirt.engine.core.vdsbroker.VdsManager] (EE-ManagedThreadFactory-engine-Thread-827644) [] Host 'v3' is not responding.
