There has been lot's of discussion about that this week. I had same problem with Opteron G3->Epyc conversion. There steps were suggested to me and they worked and you problem is similar: - set HE global maintenance mode - set one of the hosted-engine hosts into maintenance mode - move it to a different cluster - shutdown the engine VM - manually restart the engine VM on the host on the custom cluster directly executing on that host: hosted-engine --vm-start - connect again to the engine - set all the hosts of the initial cluster into maintenance mode - upgrade the cluster - shut down again the engine VM - manually restart the engine VM on one of the hosts of the initial cluster - move back the host that got into a temporary cluster to its initial cluster As first step I would add that you create new cluster which already has 4.3 level and CPU Type you want so already can check if cluster accepts nodes. -Juhani _______________________________________________ Users mailing list -- [email protected] To unsubscribe send an email to [email protected] Privacy Statement: https://www.ovirt.org/site/privacy-policy/ oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/[email protected]/message/VFWTYTLXCLN3DGUH5ENLWVK34SHPZAC2/
