[ovirt-users] Engine HA-Issues

[Kasturi Narra]

Hi ,

  Can you please check the following. Following could be one of the reason
why HE vm restarts every minute.

Check the error or engine health state. If it’s to do with Liveliness
check, then this is mostly an issue connecting to engine.

- Check if engine FQDN is reachable from all hosts

-  curl -v http://<engine-fqdn>/ovirt-engine/services/health - does this
return ok?

- Access the HE console and check if ovirt-engine is running.

- Check /var/log/ovirt-engine/server.log or
/var/log/ovirt-engine/engine.log if there are errors starting ovirt-engine


Thanks

kasturi
