I have inherited the admin duty to maintain a a small oVirt cluster featuring 2 nodes running oVirt 4.5.4 based on the CentOS Stream (using the official Node ISOs) running on physical machines, including a hosted engine. Sadly, the documentation is a bit on the "light side" and the official oVirt documentation can be overwhelming at times.
As CentOS Stream 8 is no longer supported we would like to migrate the nodes to either CentOS Stream 9 using the NG node ISOs or to Rocky Linux 9 - but I guess using the official ISOs seems like the smoothest path. Still, I would like to know what the general steps are to migrate without setting up a entirely fresh cluster. Is it possible to migrate by setting up an CentOS Stream 9 node in the existing cluster and to deploy a new engine from there? Is it possible to migrate VMs without downtime in this process? Ideally, does anyone have some kind of step-by-step guide to get from CentOS Stream 8 to 9 using the oVirt Node ISOs? Or is it possible to upgrade the existing nodes to CentOS Stream 9 and deploy a new hosted engine from there without creating an entirely new node? And yeah, I have already searched this list for answers (https://lists.ovirt.org/archives/list/[email protected]/thread/BE5BS4MJSJ4F4MEL246YTQ434K46XWF4/#BE5BS4MJSJ4F4MEL246YTQ434K46XWF4) but that thread lacks some the mentioned details. _______________________________________________ Users mailing list -- [email protected] To unsubscribe send an email to [email protected] 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/[email protected]/message/BX3DZUQ5KFL5M4LXXAMJIV2E3D7XMV26/
