I'm suspect the host-id is out of sync in the engine now. changing the host-id locally isn't supported. The engine is the only source of id assignment.

Oh, thanks! You put me on the right way! Now it works:

Steps that I did:

- reinstall + deploy vm03

- manually set from maintenance to none on vm03

- reinstall + undeploy vm04 (I left it deployed again last time, trying to remove it)

Then I found the problem: vm03 hosted-engine conf (/etc/ovirt-hosted-engine/hosted-engine.conf) had host_id set to 4 which conflicted with vm04 host_id. So I changed it to 2 (the only one free), restarted ovirt-ha-agent (and broker just to be sure) and it worked! Now from vm-status I see vm01,02 and 03 with 3400 as priority and I can migrate the HE vm to any of them! 

Thanks a lot for your kind help, Roy!

Can you share the deploy logs of vm03? /var/log/ovirt-engine/host-deploy/

Is there an /etc/ovirt-hosted-engine/hosted-engine.conf at all?

Hello Roy, I forgot to mention that I already reinstalled (several times) vm03 from the gui with the deploy option checked, but there's no way it appears there. For the record vm04 was the first host deployed (from cli) after the initial vm01 installation, then vm02 and then 03.

vm03 is missing here from the status. Can you reinstall it from UI (if you added the host vm03 then just go to Management menu and click reinstall, choose 'Deploy' Option) - After its done, when the host is activated  you'll need to manually switch the host out of maintenence (we have a bug on it - solved in master already)

Hello 

Still playing a bit with oVirt, my cluster is ovirt+gluster with a replica 3 glusterfs for the engine (on vm01, vm02 and vm03) and 4 hosts for the data glusterfs and running virtual machines (vm01, vm02, vm03 and vm04). Now, by mistake, I deployed hosted-engine on vm04 but I don't want to have the engine on a machine without local data + it's not working correctly (weight 0 and marked as in maintenance). Now, I've already tried to reinstall it from the the GUI marking the "Undeploy" check, reinstall vm03 marking the "deploy" check but nothing seems to work. Here it is the hosted-engine --vm-status output from vm04. What can I do to deploy correctly the hosted engine on vm03?
