Testing on CloudStack provider/driver (nested labs) never exposes this bug, as sending the force stop VM to parent ACS lab, doesn't return error, so nested hypervisor is always marked as Down - and VM HA would begin - i.e. we could never catch this bug in virtual/ACS env/testing. So when it comes to "ok we should fence the host" - first ask "are you dead/off" - if yes, fine continue, if not, do ipmi/redfish/cloudstack STONITH, then check to make sure host is dead - do NOT relly on status code/error returned from IPMI/Redfish/ParentACS - do explicit check: - no unpredictable errorts - works on top of all drivers (ipmi/redfish/cloudstack) - does an explicit check and then proceeds. - if no answer/check doesn't return any results - do not proceed, error out (for safety reasons) -- This is an automated message from the Apache Git Service.
