Also, I think this happened when I was upgrading ovirt1 (last in the gluster cluster) from 4.3.0 to 4.3.1 . The engine got restarted , because I forgot to enable the global maintenance. >Sorry, I don't understand >Can you please explain what happened? I have updated the engine first -> All OK, next was the arbiter -> again no issues with it. Next was the empty host -> ovirt2 and everything went OK. After that I migrated the engine to ovirt2 , and tried to updated ovirt1. The web showed that the installation failed, but using "yum update" was working. During the update via yum of ovirt1 -> the engine app crashed and restarted on ovirt2. After the reboot of ovirt1 I have noticed the error about pinging the gateway ,thus I stopped the engine and stopped the following services on both hosts (global maintenance): ovirt-ha-agent ovirt-ha-broker vdsmd supervdsmd sanlock Next was a reinitialization of the sanlock space via 'sanlock direct -s'. In the end I have managed to power on the hosted-engine and it was running for a while. As the errors did not stop - I have decided to shutdown everything, then power it up , heal gluster and check what will happen. Currently I'm not able to power up the engine: [root@ovirt1 ovirt-hosted-engine-ha]# hosted-engine --vm-status !! Cluster is in GLOBAL MAINTENANCE mode !!
