Question:
How do you remove a Worker from running a job on-the-fly while the job us running? For example, have it finish whatever frame it's working on then be excluded from the rest of the job?
Answer
Lock the Worker, but do not purge the running jobs from it. That will have the Worker complete the existing frames it is rendering and not accept new ones. It is the "nice" way to take a Worker off of a farm.
Steps:
1) Launch the QubeGUI
2) Select the Host/Worker Layout tab
3) Right-click on the Worker(s) to change and select "Lock All..." from the popup menu.
4) Say "no" when asked to purge running jobs
