I reinstalled OS all nodes CentoOS 8 streams. installed cockpit engine and ran through HCI deploy wizard with gluster. this deployed 4.4 version of engine.. then said 4.5 version available. I try to add hosts and get error "Error while executing action: Server thor.penguinpages.local is already part of another cluster." (or other node). I ssh into ovirt engine host and attempt to ssh from that host to three nodes of HCI cluster and it works fine. I added ssh keys for passwordless login but no change I change cluster then datacenter to 4.5. Then attempt to run upgrade but get same error. Seems like chicken / egg issue. I can't get nodes. I can't upgrade 4.4. to 4.5 because I have no nodes to allow maintenance mode. And engine shows "no updates" needed [root@ovirte01 ~]# yum update Last metadata expiration check: 1:39:16 ago on Mon 08 Mar 2021 08:36:40 AM EST. Dependencies resolved. Nothing to do. Complete! Suggestions?
