EFFICIENT CLUSTER UPGRADE AND DOWNGRADE
This abstract first appeared for US patent application 20250103373 titled 'EFFICIENT CLUSTER UPGRADE AND DOWNGRADE
Original Abstract Submitted
an example methodology includes declaring a node in a cluster of multiple nodes as a lead node to perform a cluster upgrade. while the lead node is performing the upgrade operations, the remaining nodes in the cluster continue to provide the cluster services. the upgrade operations on the lead node include migrating applications on the lead node to one of the other nodes in the cluster and performing upgrade of the lead node. in some cases, the upgrade operations include rebooting the lead node with a new os image and installing new versions of the applications or re-installing the same applications on the lead node. the upgrade operations on the lead node may also include, once the lead node is upgraded, stopping applications and cluster services on the other nodes in the cluster, creating a new cluster that includes the lead node, and starting the applications on the lead node.
