Hi all. We are running Rancher 2.6.9 and upgraded on of the clusters managed by rancher from 1.23.15 to 1.24.10 We saw a lot of things going wrong. Nodes had trouble communicating to each other, Some storage mounts ( Ceph block storage ) didn't want to unmount. We basically had to restart all our nodes one by one to recover everything. Has anyone else seen such behaviour?
We do know that the cri-docker replaced the docker shim part, could this be a root cause of it?
