Yesterday we had a storage crash that caused our hosted engine to stop and not auto-restart. We manually restarted it and this morning, all elements are showing a status of either question mark '?' or a red down chevron.We are running version oVirt Engine Version: 3.5.0.1-1.el6.We are chasing it down and see this in the log:2020-04-01 10:15:53,060 WARN [org.ovirt.engine.core.vdsbroker.VdsManager] (DefaultQuartzScheduler_Worker-23) Failed to refresh VDS , vds = e98f8f1d-dd1d-47c4-b039-d6eaaf578317 : hv-06, VDS Network Error, continuingAny insight into what might be causing this or the fix would be appreciated.***Mark Steele
