Hi, I were upgrading oVirt from 3.6.4.1 to 3.6.5. The engine-vm was running on host02. These are the steps that I've done: 1. Set hosted engine maintenance mode to global 2. Accessed engine-vm and upgraded oVirt to latest version 3. Run 'reboot' in engine-vm 4. After about 10 minutes, the engine-vm still doesn't boot, so I set hosted engine maintenance mode back to none. 5. After another 10 minutes, the engine-vm still doesn't boot, so I restarted host02, host01 then host03 before the engine-vm would be accessible again. I then have to activate host01 and host03 again. Here are the log files from ovirt-hosted-engine-ha folder: - host01: https://gist.github.com/weeix/d73aa8506b296c27110747464ea33312 - host02: https://gist.github.com/weeix/c1b7033f07fb104fdd483cf7ea3a7852 How to correctly restart the engine-vm when we need to? -- Wee
