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.
