Fwd: How to deploy hosted-engine to the second and later host machines
Dear Didi
Even if you never heard about hosted-engine in previous versions and 4.1 was your first attempt? Any suggestions for improvement to make it easier to find?
Sorry to late reply. I notice that I forget to add "users <users@ovirt.org>" as a destination. The inquiry of the other day was about oVirt 4.0. Yesterday I installed 4.1 for the first time. I think that if I had been able to deploy self hosted engine not only when reinstalling host but also when adding new host, I could have noticed. Or it may be useful to pop up the deployment method of self hosted engine when adding new host is completed.

e.g. that if the storage domain is not empty, a message will be emitted saying something like: "To add this host as an additional one to an existing hosted-engine HA cluster, please use the engine web administration ui or the API/SDK".
It seems to be a very appropriate explanation when reading after understanding, but it may be better to ready specific steps.For example, this is one example among many: "In particular, when creating a new host from the engine web administration ui, please select "Deploy" on the self hosted engine tab." Also, "hosted-engine --deploy --config-append=answers.conf" was an error from cli, but "hosted-engine --deploy" wasn't an error, so I almost created a new hosted-engine using "hosted-engine --deploy" to the second and later host machines.
From the above, It wil be better to warn also when running "hosted-engine --deploy".

Dear lan and Didi
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.
No, sorry for not being clear. I referred to the engine web admin ui (and also API/SDK). Thanks, Ian, for your reply explaining this.
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.
Even if you never heard about hosted-engine in previous versions and 4.1 was your first attempt? Any suggestions for improvement to make it easier to find?
I'm grateful for your support.
You might want to open one or more RFEs for some clarifications in the interface - both command line and cockpit - e.g. that if the storage domain is not empty, a message will be emitted saying something like: "To add this host as an additional one to an existing hosted-engine HA cluster, please use the engine web administration ui or the API/SDK".

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. Regards Tatsuya 2017-03-27 12:05 GMT+09:00 Tatsuya <suginami@gmail.com>:

Hi Tatsuya, you should see it also adding new hosts, it should look like this: https://raw.githubusercontent.com/oVirt/ovirt-site/30c70a9076f94113469401a51... 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/30c70a9076f94113469401a51... 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?
Or it may be useful to pop up the deployment method of self hosted engine when adding new host is completed.

Hi Simone
you should see it also adding new hosts, it should look like this: https://raw.githubusercontent.com/oVirt/ovirt-site/30c70a907 6f94113469401a51cafdfc7be8fbedd/source/images/2017-02-16- hyperconverged-ovirt-with-ovn-picture17.png <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
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.
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/30c70a907 6f94113469401a51cafdfc7be8fbedd/source/images/2017-02-16- hyperconverged-ovirt-with-ovn-picture18.png <https://raw.githubusercontent.com/oVirt/ovirt-site/30c70a9076f94113469401a51cafdfc7be8fbedd/source/images/2017-02-16-hyperconverged-ovirt-with-ovn-picture18.png>
Yes, I noticed this icon soon. It's very good.
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.'
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. 2017-03-27 18:28 GMT+09:00 Simone Tiraboschi <stirabos@redhat.com>:
