Adding Sahina here.

Thanks for the documentation pointer about RHHI.
I was able to successfully setup all three Nodes. I had to edit the final 
gdeploy File, as the Installer reserves 20GB per arbiter volume and I don't 
have that much space available for this POC.

The problem now is that I don't see the third node i.e. in the Storage / 
Volumes / Bricks view, and I get warning messages every few seconds into the 
/var/log/ovirt-engine/engine.log like:

2018-02-13 15:40:26,188+01 WARN

'cab4ba5c-10ba-11e8-aed5-00163e6a7af9'

Of course I cannot add the third node as normal oVirt Host as it is slow, has 
only minimal amount of RAM and the CPU (AMD) is different than that one of the 
two "real" Hypervisors (Intel).

Is there a way to add the third Node only for gluster management, not as 
Hypervisor? Or is there any other method to at least quieten the log?

thanks,

Re: [ovirt-users] CentOS 7 Hyperconverged oVirt 4.2 with Self-Hosted-Engine with glusterfs with 2 Hypervisors and 1 glusterfs-Arbiter-only

2018-02-12 Thread Martin Sivak
Hi,

this should work according to my gluster colleagues.

The recommended way to install this would be by using one of the
"full" nodes and deploying hosted engine via cockpit there. The
gdeploy plugin in cockpit should allow you to configure the arbiter
node.

The documentation for deploying RHHI (hyper converged RH product) is
here: 
https://access.redhat.com/documentation/en-us/red_hat_hyperconverged_infrastructure/1.1/html-single/deploying_red_hat_hyperconverged_infrastructure/index#deploy

Best regards

Martin Sivak
