Hello,

I updated all my 3 CentOS 4.4.5 hosts to 4.4.6.

Or at least upgrading them from the GUI I see now they are on CentOS 8.4 and:

[root@ov200 ~]# rpm -qa| grep 4.4.6
ovirt-release44-4.4.6.3-1.el8.noarch
ovirt-host-4.4.6-1.el8.x86_64
ovirt-host-dependencies-4.4.6-1.el8.x86_64
[root@ov200 ~]#

How to see from the webadmin GUI or from the Host Console that they are indeed 4.4.6?

If I try to set cluster compatibility version to 4.6 I get:

Error while executing action: Cannot change Cluster Compatibility Version to higher version when there are active Hosts with lower version.
-Please move Host ov300, ov301, ov200 with lower version to maintenance first.

I don't remember the need of giving downtime to get new cluster version...

Or what are further requirements (and benefits....) to upgrade to 4.6?

Thanks,

Gianluca
