It is indeed true that some scenarios, like upgrading a self hosted engine environment composed by only a single host, are not coverable and need some extra work, but the single host environment is usable Did you miss this perhaps for RHV 4.4 (and the same for 4.3): https://access.redhat.com/documentation/en-us/red_hat_hyperconverged_infrastructure_for_virtualization/1.8/html/deploying_red_hat_hyperconverged_infrastructure_for_virtualization_on_a_single_node/index ?

Hi, we have mentioned several times that it doesn't make sense to oVirt on a single host setup. So you really need to add 2nd host to your setup, move the 1st host to Maintenance and execute Enroll certificates.

[ovirt-users] Re: ovirt-engine and host certification is expired in ovirt4.0
From what I observed (but it's not something I try often), if you try to enable maintenance on a host and have VMs on it, it will try migrating the VMs first, which is a copy-first, state-transfer-afterwards process. So if there is no migration target available or if the copying and state-transfer fail, the VM will simply continue to run on the original host... and the host will refuse to go into maintenance. It doesn't solve your problem, but the loss of service you fear shouldn't happen either... except sometimes oVirt seems to have bugs or the resulting network activity cause confusion. Ah, perhaps this is important: I've only ever tried that by setting a host into maintenance (typically for patch updates) via the GUI. I am far less convinced that VM migration would also be triggered if you use the 'hosted-engine --set-maintenance --mode=local' variant on the host that runs the HostedEngine VM. That might just make it unavailable for newly started VMs. ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/7D6XC4YHIKMWSCJWZC2TJFMMD27PT4LD/
[ovirt-users] Re: ovirt-engine and host certification is expired in ovirt4.0
hello , thank you for your reply, i am not try to set the host into maintenance because many services is running on the host. my question is if i set the host into maintenance mode is it all of the server running on the host may be shutdown by itself because there is no other host is available on my ovirt-engine. in my case some of the vm server have the problem with no response so i cannot shutdown that server ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/EL6GSOL4XKHM7GS3KFHMQO3DKJXMYHWB/

Have you tried to set the host into maintenance and then "Enroll Certificates" from the UI ?
