Hi Folks, cross-posting for reacj. After upgrading to 2.7.5 recently, it was realized that one of the RKE clusters (all VMware VM's) was at an unsupported version prior to upgrade (1.22). The cluster, and all connection to it, has effectively ceased to work or connect. I saw one article out there about potentially manually upgrading the nodes to get to a supported version that Rancher will work with again. The error is:"Cluster agent is not connected" My question: what is the fix/upgrade path for a cluster that is unsupported when Rancher is upgraded? My issue is exactly this on here: https://github.com/rancher/rancher/issues/41292 What's lost on me at the moment is if this is possible to fix since the cluster was made with the UI or if there is a way upgrade manaully?? I have tried: - Updating through the UI - hit the PSP issue noted in the forum thread - Tried to deploy a new node with all roles at the higher k8s version - this just hangs registering Is there a way to fix this manually or am I just out of luck with this and Rancher will force me to delete it and re-create? Thanks for any advice or help - I'm a bit stuck at the moment.
