Upgrade datacenter from 3.6 to 4.0
by Arnaud Lauriou 26 Aug '16

26 Aug '16

Hi, What is the best way to upgrade a datacenter from ovirt 3.6 to 4.0 ? Upgrade engine, hosts then cluster ? If right, how do you upgrade a host running ovirt 3.6.7 ? Simple upgrade or fresh install ? During the update process of a cluster, some hosts will be in 3.6.7 and others in 4.0.2, is it a problem for migrating VMs ? Found docs about engine upgrade but not a lot about host and cluster. Thanks, Arnaud

I've just upgraded Ovirt3.6 to 4.0.2 and I can't get the dashboard to work. The dashboard page displays this error: Could not fetch dashboard data.

Enable Gluster service during hosted-engine deploy
by Renout Gerrits 25 Aug '16

25 Aug '16

Hi all, Is there a way to enable the Gluster Service for a cluster in the hosted engine deploy? In the config append you make the gluster service available with: OVESETUP_CONFIG/applicationMode=str:both. But how would one enable it? I would like to enable it automatically. Now I change it afterwards with API, but after the change I have to put the hosts into maintenance and activate them again. It would seems there must be a better way to do this. Thanks, Renout
