This section explains how to use the qq upgrade_cluster command.


Run a cluster upgrade to the image specified by the provided path


qq upgrade_cluster [-h] [--path PATH] [--no-monitor] [--rolling] [--num-nodes-to-reboot NO_COMMAND_NUM_NODES_TO_REBOOT] {prepare,commit} ...


Flag Name Required Description
--path No FS path to upgrade image
--no-monitor No Skip monitoring the upgrade
--num-nodes-to-reboot No Using the --rolling flag lets you specify the number of nodes to reboot at a time. The number of nodes must be greater than 0 and less than or equal to the number of node failures that your cluster permits. By default, this value is the number of permitted node failures minus 1 (1 node minimum).
