[ovirt-users] Installation of oVirt 4.1, Gluster Storage and Hosted Engine

Fri Jul 7 16:31:42 UTC 2017

Hi to all,

I have an old installation of oVirt 3.3 with the Engine on a separate 
server. I wanted to test the last oVirt 4.1 with Gluster Storage and 
Hosted Engine.

Followed the following tutorial:

http://www.ovirt.org/blog/2017/04/up-and-running-with-ovirt-4.1-and-gluster-storage/

I have 3 hosts as shown in the tutorial. Installed CentOS 7.3, the oVirt 
4.1 repo and all required packages. Configured passwordless ssh as stated.
Then I log in cockpit web interface, selected "Hosted Engine with 
Gluster" and hit the Start button. Configured the parameters as shown in 
the tutorial.

In the last step (5) the Generated Gdeply configuration (note: replaced 
the real domain with "domain.it"):

When I hit "Deploy" button the Deployment fails with the following error:

What I'm doing wrong? Maybe I need to initializa glusterfs in some way...
What are the logs used to log the status of this deployment so I can 
check the errors?

Thanks in advance!
