Hi,
We have a cluster with 6 nodes. One of the nodes re-joined the cluster after being reinstalled updated a few days ago and when we realize that all other nodes of the cluster were updated too!
Proxmox launched automatically "apt upgrade" & "apt dist-upgrade" commands, by this order at the same time to all nodes, upgrading even the kernel (but not restarting the nodes).
