I’m trying to install latest oVirt release on a cluster lab.

 

I have 6 servers and I need to use gluster from hyperconverged hosted engine lab, all of them have volumes for gluster storage, apart OS disks.

 

Servers are installed with ovirt-node-ng-installer-ovirt-4.1-pre-2017051210 iso image.

After installation, full update.

 

I’m try to follow the guide in : http://www.ovirt.org/blog/2017/04/up-and-running-with-ovirt-4-1-and-gluster-storage/

In this guide, I can seen in the host selection, the possibility to add more than three hosts to the cluster.

In current cockpit version, I can’t see this.


Yes, we changed it to a 3 host setup only and removed the possibility to add more hosts in the initial setup.
 

 

These are cockpit components, installed in all six servers:

 

cockpit-ws-140-1.el7.centos.x86_64

cockpit-system-140-1.el7.centos.noarch

cockpit-140-1.el7.centos.x86_64

cockpit-dashboard-140-1.el7.centos.x86_64

cockpit-storaged-140-1.el7.centos.noarch

cockpit-ovirt-dashboard-0.10.7-0.0.18.el7.centos.noarch

cockpit-bridge-140-1.el7.centos.x86_64

 

Two questions:

 

Must I proceed with only three servers and only after add the remainder three to the cluster, to have distributed&replicated gluster solution or I must change something in the first installation phase, to add all six servers from the beginning ?


Please proceed with 3 servers, and then add the remaining 3 to the cluster from the oVirt UI.

You can add additional gluster volumes from the 3 new servers and create new storage domain.

If you want to expand the gluster volume that was created in the initial setup (i.e add new bricks to it) - it's advised to add bricks while there are no VMs running (this is if you're on a gluster version =3.8, as there's a bug with rebalance with ongoing I/O)
 

 

In the second cockpit screen there aren’t default repo/packages, must I leave it blank ? (servers are already updated).


Yes, leave this blank
 

 

Thanks in advance for any hints.

 

Roberto
