Hi,

removed partition signatures with wipefs and run deploy again: this 
time the creation of VG and LV worked correctly. The deployment

In start/stop/restart/reload services it complain about "Could not 
find the requested service glusterd: host". GlusterFS must be 
preinstalled or not? I simply installed the rpm packages manually 
BEFORE the deployment:

yum install glusterfs glusterfs-cli glusterfs-libs 
glusterfs-client-xlators glusterfs-api glusterfs-fuse

but never configured anything.
Looks like it failed to add the 'glusterfs' service using firewalld 
and can we try again with what Gianluca suggested ?

Can you please install the latest ovirt rpm which will add all the 
required dependencies and make sure that the following packages are 
installed before running with gdeploy ?

yum install vdsm-gluster ovirt-hosted-engine-setup gdeploy 
cockpit-ovirt-dashboard

For firewalld problem "ERROR: Exception caught: 
org.fedoraproject.FirewallD1.Exception: INVALID_SERVICE: 'glusterfs' 
not among existing services Services are defined by port/tcp 
relationship and named as they are in /etc/services (on most 
systems)" I haven't touched anything... it's an "out of the box" 
installation of CentOS 7.3.

Don't know if the following problems - "Run a shell script" and 
"usermod: group 'gluster' does not exist" - are related to these... 
maybe the usermod problem.
You could safely ignore this and this has nothing to do with the 
configuration.

Thank you again.
Simone

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

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

why this failure.

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.

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.
