Hi,
I have figured it out that the root cause of the deployment failure is timing
out while the hosted engine was trying to connect to host vis SSH as shown in
engine.log (located in
/var/log/ovirt-hosted-engine-setup/engine-logs-2019-12-31T06:34:38Z/ovirt-engine):
2019-12-31 15:43:06,082+09 ERROR

failed, verify that the host is reachable (IP address, routable address etc.)
You may refer to the engine.log file for further details.]
The FQDN of hosted engine (alice-ovirt-engine.sdfarm.kr
<http://alice-ovirt-engine.sdfarm.kr/>) is resolved as well as the host
(alice-ovirt-01.sdfarm.kr <http://alice-ovirt-01.sdfarm.kr/>) and SSH is the
one of services that are allowed by firewalld. I believe the rules of firewalld
is automatically configured during the deployment to work with hosted engine
and the host. Also root access is configured to be allowed at the first stage
of deployment.
I was just wondering how I can verify the hosted engine can access to the host
at this stage? Once it fails to deploy, the deployment script make all things
rolled back (I believe it cleans all up) and the vm-status of hosted-engine is
un-deployed.
Thank you in advance,
Best regards,
Sang-Un
