How to deploy hosted-engine to the second and later host machines
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 ...

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 hosted-engine host: https://bugzilla.redhat.com/1366183 Best, -- Didi
Hello Didi. Thank you for the information.
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 hosted-engine host:
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
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.

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.

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".
