Does the use of node label contain a notion of “affinity”. In other words, I would like a build to go to node A always, unless node A is unavailable.
I implemented my own failover by using a node label parameter with a default node of A and a “possible nodes” of the failover node.

I guess this gets to the heart of my question... If I make it so that an old job won't run on builder, will it fail over to the newly created node? Yes, it will switch freely from one node to another unless you have tied the job to a specific node. That's one of the reasons to tie a job to a capability based label rather than tying it to a specific node name. Mark Waite That is, will old jobs run on the new node, if cajoled properly, or will they just fail altogether?

The "Usage" field of the master node configuration should have a pick list with two choices, either "Use this node as much as possible" (the default), or "Only build jobs with label expressions matching this node". That will tend to keep most jobs off your master node (at least it does for me).

I now have two new agent nodes set up and want to move old jobs off the master, so the master won't be used for any building (just admin). How do I prevent jobs from running on the master? Do I just set "number of executors" to zero? For new jobs, I see the choice in their configuration allowing me to decide where to run the job, so I can force it to run on the agent node not the master. I understand old jobs are supposed to run on the master, but I don't want them to any more. Even cloned (new) jobs seem to not have the "Restrict where this job runs" configuration option, so I assume they will run on the master (as did the job from which they were cloned.) What are my options? This plugin seems to be one possibility for setting the node at build time (I imagine I can set its default to specify a new node for building?) https://wiki.jenkins-ci.org/display/JENKINS/NodeLabel+Parameter+Plugin<https://urldefense.proofpoint.com/v2/url?u=https-3A__webmail.novantas.com_owa_redir.aspx-3FSURL-3DbccvBaZmiAUZEiOjb7fb5V0hm90n-5FX4zGXw8tWkw-2D8ka1WNgEcbTCGgAdAB0AHAAcwA6AC8ALwB3AGkAawBpAC4AagBlAG4AawBpAG4AcwAtAGMAaQAuAG8AcgBnAC8AZABpAHMAcABsAGEAeQAvAEoARQBOAEsASQBOAFMALwBOAG8AZABlAEwAYQBiAGUAbAArAFAAYQByAGEAbQBlAHQAZQByACsAUABsAHUAZwBpAG4A-26URL-3Dhttps-253a-252f-252fwiki.jenkins-2Dci.org-252fdisplay-252fJENKINS-252fNodeLabel-252bParameter-252bPlugin&d=DQMFaQ&c=3mGIBQKb1eS1YDHb7ax3kFkT2UAGBJ12p2lcECIjhXk&r=SXz9subj7EUWDFIuiAjJSXBLM9pAzGIduhHWvfq5re0&m=nXhfG9PkqmRpZIuD5R5-RGLY9x3zWMXVPKMj_OmzvYA&s=th0wJemjUB73CcgPWJcL-leHSh66pbDjRn2BcpDR35s&e=> Will that work with old jobs, causing them to run on one of the new agent nodes instead of the master?
