The second host tries to start the engine when you stop the broker on the first host (because it is not getting any updates and thinks that the host is dead). But the engine is still running so sanlock prevents the VM from starting on the second host. That puts the host to EngineUnexpectedlyDown for ten minutes. The score is reduced to 0 while the host is in that state. There is one known issue here and that is we do not know the reason for the VM crash. We can't distinguish sanlock protection from a real crash here. *** This bug has been marked as a duplicate of bug 1150087 *** |

Actual results: HE VM not started on second host after service ovirt-ha-broker stopped on host that is running HE VM. Expected results: HE VM should be started on second host and score should not be zero. Additional info: logs attached.
