Hi,

We have managed to stabilize the DNS udpate in out network. Now the current situation is.

I have 3 hosts that can run the engine (hosted-engine).

They were all in the 10.8.236.x. Now i have moved one of them in the 10.16.248.x.

If i boot the engine on one of the host that is in the 10.8.236.x the engine is going up with status "good". I can access the engine UI. I can see all my hosts even the one in the 10.16.248.x network.

But if i boot the engine on the hosted-engine host that was switch to the 10.16.248.x the engine is booting. I can ssh to it but the status is always " fail for liveliness check".

The main difference is that when i boot on the host that is in the 10.16.248.x network the engine gets a address in the 248.x network.

On the engine i have this in the /var/log/ovirt-engine-dwh/ovirt-engine-dwhd.log

019-07-23 09:05:30|MFzehi|YYTDiS|jTq2w8|OVIRT_ENGINE_DWH|SampleTimeKeepingJob|Default|5|tWarn|tWarn_1|Can not sample data, oVirt Engine is not updating the statistics. Please check your oVirt Engine status.|9704

the engine.log seems okey.

So i need to understand what this " liveliness check" do(or try to do) so i can investigate why the engine status is not becoming good.

The initial deployment was done in the 10.8.236.x network. Maybe is as something to do with that.

Thanks & Regards

Carl

I'm assuming it fails for the same reason you've stated initially  -
i.e. ovn-controller is involved; if it is not, disregard this msg :)
