Hosted Engine: Add another host
Hi, I have a hosted-engine setup on one host. Today I try to add another host from the UI but this gives me some errors without detail. Is there a way to add a new host from the shell? Not a node [1] because I plan to use docker as well on the host, it's a test environment. Or is it better to install the host as node? cheers gregor [1] http://www.ovirt.org/node/

It would be useful to understand the errors you get in web ui, because they could be similar also in command line deploy.... I think you can follow what happened in 3.6 as described here: https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Virtualizat... For oVirt and CentOS I think that these below should be the commands to run on your second host (see the other details explained in the web page above, that could be different in some way in 4.0 vs 3.6) # yum install http://resources.ovirt.org/pub/yum-repo/ovirt-release40.rpm # yum install ovirt-hosted-engine-setup # hosted-engine --deploy HIH, Gianluca

Deploying additional hosted-engine hosts has been deprecated, deploying from the web ui is the recommended way. Could you please check host-deploy logs on the engine VM to check what went wrong?

Hi, finally these are my steps to add a host to my cluster: - Install CentOS 7 minimal - Configure NTP (otherwise the installer stopped with an error) - Configure Network and DNS - Add the oVirt repo: yum -y install http://resources.ovirt.org/pub/yum-repo/ovirt-release40.rpm - Now add the host form the web management Thanks for your help and links to the resources. greetings gregor On 12/01/17 09:40, Simone Tiraboschi wrote:

Yes, this is the expected flow. If you are planning about adding a lot of hosts you could also consider evaluating the foreman integration: http://www.ovirt.org/develop/release-management/features/foreman/foremaninte...
- Install CentOS 7 minimal - Configure NTP (otherwise the installer stopped with an error)
Could you please provide more details about this?
- Configure Network and DNS - Add the oVirt repo: yum -y install http://resources.ovirt.org/pub/yum-repo/ovirt-release40.rpm - Now add the host form the web management
Thanks for your help and links to the resources.
