Good afternoon,

I was able to get the engine to run again but there are still some issues.

Following the steps detailed at http://www.ovirt.org/documentation/self-hosted/chap-Troubleshooting/ , I was able to connect to the engine console. Form there I was able to see that the engine did not have an IP address.

For some reason, the configuration for eth0 was gone. I re-created the /etc/sysconfig/network-scripts/ifcfg-eth0 file, restarted the network service. I had an IP address and could access the engine engine after that.

However, there are some issues still.

The data gluster volume is still down. I can't see any of the hosts even though I have three. Those issues force the data center to be set as non-operational. See captions below.

I think If I could get the data volume to mount properly, most of the issues would be resolved.

Any assistance would be greatly appreciated.

Thank you,

Joel

Ok.

Simone,

Please let me know if I can provide any additional log files.

Thanks for taking the time to look into this.

I don't notice anything wrong on the gluster end.

Maybe Simone can help take a look at HE behaviour?

It looks like the HE VM was started successfully? Is it possible that the ovirt-engine service could not be started on the HE VM. Could you try to start the HE vm using below and then logging into the VM console.
#hosted-engine --vm-start

Also, please check
# gluster volume status engine
# gluster volume heal engine info

Please also check if there are errors in gluster mount logs - at /var/log/glusterfs/rhev-data-center-mnt..<engine>.log

Can you try to restart the ovirt-ha-agent and ovirt-ha-broker services?

If HE still has issues powering up, please provide agent.log and broker.log from /var/log/ovirt-hosted-engine-ha and gluster mount logs from /var/log/glusterfs/rhev-data-center-mnt <engine>.log

Good morning oVirt community,

I'm running a three host gluster environment with hosted engine.

Yesterday the engine went down and has not been able to come up properly. It tries to start on all three host.

I have two gluster volumes, data and engne. The data storage domian volume is no longer mounted but the engine volume is up. I've restarted the gluster service and make sure both volumes were running. The data volume will not mount.

How can I get the engine running properly again?

Thanks,

Joel
