But this goes completely against what seems to be present inside the RHV docs, where, as described in my previous post: " If you decide to use a new host, you must assign a unique name to the new host and then add it to the existing cluster before you begin the upgrade procedure. " And also the oVirt docs that are substantially based on RHV ones: https://www.ovirt.org/documentation/upgrade_guide/index.html#SHE_Upgrading_from_4-3 " When upgrading oVirt Engine, it is recommended that you use one of the existing hosts. If you decide to use a new host, you must assign a unique name to the new host and then add it to the existing cluster before you begin the upgrade procedure. . . . It is recommended that you use one of the existing hosts. If you decide to use a new host, you must assign a unique name to the new host and then add it to the existing cluster before you begin the upgrade procedure. " So I would have in this case the same problem related to wrong fingerprint, or I should be forced to copy fingerprint before scratching the host and reuse it (if supported passing from node in version 7 to node in version 8 of the OS)..... It seems strange this problem didn't arise before... the phrase: " The upgraded host with the 4.4 self-hosted engine reports that HA mode is active,... " lets think that the host name remains consistent with a pre-existing one and as a reinstall is mandatory (7-->8) I don't see how it could work...
