Hi,

Our cluster was running fine, until we moved it to the new network. Looking at the agent.log file, it stills pings the old gateway. Not sure if this is the reason it's failing the liveliness check.

You can update the gateway address used in network test with something like:

hosted-engine --set-shared-config gateway 192.168.1.1 --type=he_local

hosted-engine --set-shared-config gateway 192.168.1.1 --type=he_shared

The first command will update the value used on the current host; the second one will update the master copy on the shared storage use by default on the host you are going to deploy in the future.

But engine health check doesn't really depend on that: it's a kind of application level ping sent over http to the engine.

You can manually check it with:

curl http://$(grep fqdn /etc/ovirt-hosted-engine/hosted-engine.conf | cut -d= -f2)/ovirt-engine/services/health

I'd suggest to check name resolution.

Please help.

Hi,

I need some help. We had a working ovirt cluster in the testing environment. We have just moved it to the production environment with the same network settings. The only thing we changed is the public VLAN. In production we're using a different subnet.

The problem is we can't get the HostedEngine Up. It does come up but it fails the LIVELINESS CHECK and its health status is bad. We can't ping even ping it. It is on the same subnet as host machines: 192.168.x.x/24:
