By looking at your image, I found that this recognition discrepancy is due
to localization.
In English, Hosted Engine was displayed even in my environment.

Yes, I noticed this icon soon. It's very good.

I'm sorry I haven't tried cli install in 4.1.1, but I think it important to
restrict it as you said.
It was a great relief for me personally to automate setting such as lvm,
glusterfs, firewalld and selinux.

There are no particular points to improve.
Thank you for your support.

Hi Tatsuya,
you should see it also adding new hosts, it should look like this:
https://raw.githubusercontent.com/oVirt/ovirt-site/30c70a9076f94113469401a51cafdfc7be8fbedd/source/images/2017-02-16-hyperconverged-ovirt-with-ovn-picture17.png
That one is from 4.1.0

There is also an explicit icon to highlight which host is running the
engine VM and which ones are ready for it:
https://raw.githubusercontent.com/oVirt/ovirt-site/30c70a9076f94113469401a51cafdfc7be8fbedd/source/images/2017-02-16-hyperconverged-ovirt-with-ovn-picture18.png

Deploying from CLI is explicitly prevented and it's pointing you to the web
UI with this message:
'Setup of additional hosts using this software is not allowed anymore.
Please use the engine web interface to deploy any additional hosts.'

Do you think it's not that clear?
Anything we can improve?

Sorry for the mistake.

In the following mail I sent earlier, the “4.0” should read “4.1.0”
and the “4.1” should read “4.1.1” instead.

I apologize for this late reply.I had been trying again from reinstalling
the host.

Thanks to you, I was able to install HostedEngine in second and subsequent
hosts.
I think that I could not find this option by myself.

I'm grateful for your support.

Re: [ovirt-users] How to deploy hosted-engine to the second and later host machines

[Ian Neilsen]

Found a working option to get second and subsequent hosts deployed with
ovirt 4.1

1-Set second host into maintenance
2-highlight second host and choose "Installation --> Reinstall", edit
params in popup and click OK
3-Ignore warning that pops up and watch the vdsm.log or look for
"Installing" status in webui
4-It should show you that the install is running, keep watching vdsm.log.
5-Click 'ok' on warning and wait patiently for install to finish.

Second node comes up and is active.

Having same issue here also.

hosted-engine --deploy via cli is no longer available and hosted deploy via
UI does not work.
Host 2 is present in the engine manager and can be controlled via GUI,
however engine manager vm cannot be moved to host 2 due to hosted-engine
--deploy needing to be run.

Re: [ovirt-users] How to deploy hosted-engine to the second and later host machines

Hello Didi.

Thank you for the information.

> There is an option to configure hosted-engine when adding a host from

> https://bugzilla.redhat.com/1366183

Does web ui include Cockpit UI?

I tried to install additional Hosted Engine from Cockpit UI but I received
a same error which I received on cli.
> [ ERROR ] The selected device already contains a storage domain.

I tried from "Start" link, but must I use "Deploy with Gluster *" like
following link?
http://www.ovirt.org/images/wiki/Deploy-With-Gluster.png?1475063791

* In my case, it's "Hosted Engine with Gluster"

I also tried "Hosted Engine with Gluster", but when I ran "deploy" after
option selection,
"Deployment failed" was displayed in a moment and I could not find a log,
so I gave up.

Also, when running "Hosted Engine with Gluster", many things are done
automatically
(create LV and create GlusterFS volume etc.), so I believe there is just
another way to simply add hosted engine.

If you know, could you please tell me which link should be executed to add
hosted-engine?

Thanks,
Tatsuya

There is an option to configure hosted-engine when adding a host from
the web ui.
In 4.1 this is the only way to add a 

[ovirt-users] How to deploy hosted-engine to the second and later host machines

[Tatsuya]

Hi,

I'm running oVirt 4.1.0.4-1. I'm building oVirt+GlusterFS(replica 3 Volume)
configuration for testing.

Each machine spec is as follows.
 CPU: 2core
 Memory: 8GB
 Disk: 120GB
 OS: CentOS7.3

Each host name is host1, host2, host3.

I installed Hosted Engine successfully in host1, but I couldn't install it
in host2 and host3.

In version 4.0, as described below, since it is asked whether or not it is
an additional host at the time of deployment,
hosted_engine could be added to the second and later node without any error.

*** oVirt 4.0 ***

[root@host2 ~]# hosted-engine --deploy --config-append=answers.conf
...
  The specified storage location already contains a data domain. Is
this an additional host setup (Yes, No)[Yes]?
[ INFO  ] Installing on additional host

  iptables was detected on your computer, do you wish setup to
configure it? (Yes, No)[Yes]: No

  Host FQDN:  [host2.jitaku.test]:
[WARNING] Failed to resolve host2.jitaku.test using DNS, it can be resolved
only locally

  --== CONFIGURATION PREVIEW ==--

  Engine FQDN: ovirt-engine.jitaku.test
  Bridge name: ovirtmgmt
  Host address   : host2.jitaku.test
  SSH daemon port: 22
  Gateway address: 192.168.12.1
  Host name for web application  : hosted_engine_2
  Storage Domain type: glusterfs
  Host ID: 2
  Image size GB  : 10

But oVirt 4.1 asks for nothing and return error that host1 already has data.

I tried it from Virtualization> Hosted Engine> Standard of Cockpit UI, but
I received the similar error.
How can I deploy hosted-engine on multiple hosts? I'm sorry if I made
something misunderstood.

Thanks.
