I stopped the VMs and then "hosted-engine --vm-shutdown" followed by "hosted-engine --vm-start", I thought that would restart everything, but apparently not.

Now I just did "systemctl status ovirt-ha-broker" and got this ugly thing:

This is harmless, can be ignored. It most likely happens because you configured to send notifications via email to an unreachable mail server - the default is localhost. I suggest to check the log for more/other errors.

And

That's not good. You might find more details it the HA logs or vdsm logs.

Is the broker error causing the agent error or vice-versa ?

All I did a couple of weeks ago was reboot the host (after having shut down the VMs and stopped the engine).

The engine and VMs seem to be working fine.

That's good - so not all hope is lost :-). But better find the root cause and handle it.

Best regards,

Thanks for all of your help.
