[ovirt-users] oVirt 4.2 upgrade procedure.

[Eduardo Mayoral]

Hi,

    I just started upgrading one of our oVirt installations from 4.1.8
to 4.2

    Engine is NOT self hosted. It is a plain CentOS 7.4 server.

    Compute hosts (10 of them) are CentOS 7.4 as well. Storage is mainly
iSCSI served from an external storage system.

    Engine upgrade was seamless. Now I want to upgrade the hosts, then
change the cluster compatibility level, then the datacenter
compatibility. Can someone confirm that this is the correct sequence?

    On the first host, I put it in maintenance mode, installed
centos-release-ovirt42 and removed centos-release-ovirt41.

    When doing the upgrade host from the web interface, I get:

2017-12-28 10:58:46,054 p=7173 u=ovirt |  Using
/usr/share/ovirt-engine/playbooks/ansible.cfg as config file
2017-12-28 10:58:46,288 p=7173 u=ovirt |  PLAY [all]
*********************************************************************

ok=0    changed=0    unreachable=0    failed=1  

Now, I see the ovirt-host package is not installed or available on the
Compute node. It is available on the ovirt-engine on repo "ovirt-4.2"
(which is installed by ovirt-release42-4.2.0-1.el7.centos.noarch)

I am a bit confused here. I thought I only needed centos-release-ovirt42
(centos-ovirt42 repo) on the compute hosts. Is that so? Has this changed
from 4.1 to 4.2?

Thank you very much for your help!
