Hi Jonathan,
To upgrade to cluster 4.5 you need a 8.3 host
Centos8.3 is not out yet, so you'll have to wait for it to be able to upgrade the cluster to version 4.5

Sorry, last time I didn't answer to the mailing list...

Here are the output: CentOS Linux release 8.2.2004 (Core)

I use the kernel-plus, because of an old raid controller. Can this be a problem?

Thanks Jonathan
Can you tell me what is the OS version of the host that you're using? (cat /etc/redhat-release)

Hello Dana,

I added a second host, and tried again, without success.

The error is unspecific, it just says: Upgrade of cluster default failed.

Here the engine.log

Hi Jonathan,
What is the error you're getting when you're trying to upgrade using the upgrade guide?
Can you also attach the engine log? (/var/log/ovirt-engine/engine.log)
Thanks,
Dana

Hello everybody,

for some days I upgrade our environment from ovirt 4.3 to 4.4.2 and now
I stuck on upgrading the host compatibility version. It show there a
compatibility until version 4.4. The VMs have a limit until version 4.5
and the cluster shows to that I can upgrade them until 4.5.

On the cluster page is also a Upgrade guide, but this fails when I try
that one. At the moment I have only one host to upgrade (no hosted
engine)...

Thanks for helping!

Jonathan
