Hi Strahil and Yedidyah,
First of all I want to thank you for helping me.
So, this is what I did:
[root@ovirt-sj-03 ~]# hosted-engine --vm-status | grep -B2 "Host ID"
Status up-to-date : True
Hostname : ovirt-sj-01.ictv.com
Host ID : 1
--
Status up-to-date : True
Hostname : ovirt-sj-03.ictv.com
Host ID : 3
From the start of deployment, I could see following ERROR messages on Host2:
VDSM:

And the
Hosted-Engine.conf file looks like this:
[root@ovirt-sj-02 ~]# cat /etc/ovirt-hosted-engine/hosted-engine.conf
ca_cert=/etc/pki/vdsm/libvirt-spice/ca-cert.pem
host_id=2
Ovirt hosted_engine network path is mounted.
What could be the reason hosted-engine.conf is missing all other entries?
Do I copy the hosted-engine.conf from host1 or host3, making sure host_id is unique (host_id=2) on Host2, and try to re-deploy?
How does the hosted-engine.conf gets loaded or from where? Am I missing a mount point? Is the deployment failing because hosted-engine.conf is empty or it’s the other way around?

'engine-cleanup' is a utility you run on the engine machine, which
does basically the opposite of 'engine-setup', and in any case cleans
up the _engine_, not any particular host. If you run it, your engine
is gone, likely forever (unless you kept backups).
What you might were looking for is 'ovirt-hosted-engine-cleanup'. This
one cleans up a host from a hosted-engine deployment. It's generally
intended to be used after a failed deployment attempt. I think it can
work well also in your case, but would first try to fix using other
means.
