I've restarted those two services across all hosts, have taken the Hosted Engine host out of maintenance, and when I try to migrate the Hosted Engine over to another host, it reports that all three hosts 'did not satisfy internal filter HA because it is not a Hosted Engine host'. On the host that the Hosted Engine is currently on it reports in the agent.log: ovirt-ha-agent ovirt_hosted_engine_ha.lib.brokerlink.BrokerLink ERROR Connection closed: Connection closed Jun 29 15:22:25 kvm-ldn-03 ovirt-ha-agent[12653]: ovirt-ha-agent ovirt_hosted_engine_ha.lib.brokerlink.BrokerLink ERROR Exception getting service path: Connection closed Jun 29 15:22:25 kvm-ldn-03 ovirt-ha-agent[12653]: ovirt-ha-agent ovirt_hosted_engine_ha.agent.agent.Agent ERROR Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/agent/agent.py", line 191, in _run_agent return action(he) File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/agent/agent.py", line 64, in action_proper return he.start_monitoring() File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/agent/hosted_engine.py", line 411, in start_monitoring self._initialize_sanlock() File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/agent/hosted_engine.py", line 691, in _initialize_sanlock constants.SERVICE_TYPE + constants.LOCKSPACE_EXTENSION) File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/lib/brokerlink.py", line 162, in get_service_path .format(str(e))) RequestError: Failed to get service path: Connection closed Jun 29 15:22:25 kvm-ldn-03 ovirt-ha-agent[12653]: ovirt-ha-agent ovirt_hosted_engine_ha.agent.agent.Agent ERROR Trying to restart agent On Thu, Jun 29, 2017 at 1:25 PM, Martin Sivak <msivak@redhat.com> wrote:
Hi,
yep, you have to restart the ovirt-ha-agent and ovirt-ha-broker services.
The scheduling message just means that the host has score 0 or is not reporting score at all.

Thanks Martin, do I have to restart anything? When I try to use the 'migrate' operation, it complains that the other two hosts 'did not satisfy internal filter HA because it is not a Hosted Engine host..' (even though I reinstalled both these hosts with the 'deploy hosted engine' option, which suggests that something needs restarting. Should I worry about the sanlock errors, or will that be resolved by the change in host_id?
Kind regards,

Change the ids so they are distinct. I need to check if there is a way to read the SPM ids from the engine as using the same numbers would be the best.

Is there any way of recovering from this situation? I'd prefer to fix the issue rather than re-deploy, but if there is no recovery path, I could perhaps try re-deploying the hosted engine. In which case, would the best option be to take a backup of the Hosted Engine, and then shut it down, re-initialise the SAN partition (or use another partition) and retry the deployment? Would it be better to use the older backup from the bare metal engine that I originally used, or use a backup from the Hosted Engine? I'm not sure if any VMs have been added since switching to Hosted Engine.
Unfortunately I have very little time left to get this working before I have to hand it over for eval (by end of Friday).

Hi Martin,
yes, on two of the machines they have the same host_id. The other has a different host_id.
To update since yesterday: I reinstalled and deployed Hosted Engine on the other host (so all three hosts in the cluster now have it installed). The second one I deployed said it was able to host the engine (unlike the first I reinstalled), so I tried putting the host with the Hosted Engine on it into maintenance to see if it would migrate over. It managed to move all hosts but the Hosted Engine. And now the host that said it was able to host the engine says 'unavailable due to HA score'. The host that it was trying to move from is now in 'preparing for maintenance' for the last 12 hours.
The summary is:
kvm-ldn-01 - one of the original, pre-Hosted Engine hosts, reinstalled with 'Deploy Hosted Engine'. No icon saying it can host the Hosted Hngine, host_id of '2' in /etc/ovirt-hosted-engine/hosted-engine.conf. 'add_lockspace' fails in sanlock.log
kvm-ldn-02 - the other host that was pre-existing before Hosted Engine was created. Reinstalled with 'Deploy Hosted Engine'. Had an icon saying that it was able to host the Hosted Engine, but after migration was attempted when putting kvm-ldn-03 into maintenance, it reports: 'unavailable due to HA score'. It has a host_id of '1' in /etc/ovirt-hosted-engine/hosted-engine.conf. No errors in sanlock.log
kvm-ldn-03 - this was the host I deployed Hosted Engine on, which was not part of the original cluster. I restored the bare-metal engine backup in the Hosted Engine on this host when deploying it, without error. It currently has the Hosted Engine on it (as the only VM after I put that host into maintenance to test the HA of Hosted Engine). Sanlock log shows conflicts
I will look through all the logs for any other errors. Please let me know if you need any logs or other clarification/information.
Thanks,
Campbell

Hi,
can you please check the contents of /etc/ovirt-hosted-engine/hosted-engine.conf or /etc/ovirt-hosted-engine-ha/agent.conf (I am not sure which one it is right now) and search for host-id?
Make sure the IDs are different. If they are not, then there is a bug somewhere.
