Hi,
reply here to both Gianluca and Kasturi.
Gianluca: I had ovirt-4.1-dependencies.repo enabled, and gluster 3.8 packages, but glusterfs-server was missing in my "yum install" command, so added glusterfs-server to my installation.
Kasturi: packages ovirt-hosted-engine-setup, gdeploy and cockpit-ovirt-dashboard already installed and updated. vdsm-gluster was missing, so added to my installation. okay, cool.
:-)
Rerun deployment and IT WORKED! I can read the message "Succesfully deployed Gluster" with the blue button "Continue to Hosted Engine Deployment". There's a minor glitch in the window: the green "V" in the circle is missing, like there's a missing image (or a wrong path, as I had to remove "ansible" from the grafton-sanity-check.sh path...)
There is a bug for this and it will be fixed soon. Here is the bug id for your reference. https://bugzilla.redhat.com/show_bug.cgi?id=1462082
Ok, thank you!
Although the deployment worked, and the firewalld and gluterfs errors are gone, a couple of errors remains:

May be you missed to change the path of the script "/usr/share/ansible/gdeploy/scripts/disable-gluster-hooks.sh" . That is why this failure.
You're right: changed the path and now it's ok.

This error can be safely ignored.
Ok
These are a problem for my installation or can I ignore them?
You can just manually run the script to disable hooks on all the nodes. Other error you can ignore.
Done it
By the way, I'm writing and documenting this process and can prepare a tutorial if someone is interested.
Thank you again for your support: now I'll proceed with the Hosted Engine Deployment.
Good to know that you can now start with Hosted Engine Deployment.
Started the Hosted Engine Deployment, but I have a different problem now.
As the installer asked, I specified some parameters, in particular a pingable gateway address. Specified the host1 gateway. Proceeding with the installer, it requires The Engine VM IP address (DHCP or Static). I selected static and specified an IP Address, but the IP *IS NOT* in the same subnet as the host1. The VMs IP addresses are all on a different subnet. The installer shows a red message:
The Engine VM (aa.bb.cc.dd/SM) and the default gateway (ww.xx.yy.zz) will not be in the same IP subnet. Static routing configuration are not supported on automatic VM configuration.
I'm starting to think that BOTH the hosts IPs and the VM IPs MUST BE ON THE SAME SUBNET.
Is this a requirement or there's a way to deal with this configuration? It's related only to "automatic VM configuration" or to oVirt in general? Once installed oVirt Engine can I have VMs on different subnet? Here are some Requirements :
1) Engine VM and the managed hosts should be on management subnet 2) Managed host should be able to resolve EngineVM hostname and vice-versa. We configure the engine appliance with DHCP or static addressing. 3) Before proceeding with hosted-engine deployment we recommend the user to have an FQDN assigned to a mac address to go via DHCP way. 4) If you are using static then IP address/ netmask /gateway based on host ones , and add entries to /etc/hosts if you do not have local DNS. Hope this helps !!! Thanks kasturi
