Click ‘Do it now’ to remove the nodes immediatelyChange the display back to ‘Show all nodes’
Job groups are used to assign specific nodes to certain jobs
Using job groupsBy default, each job group contains all nodesSelect the job group to be modifiedSelect the ‘Group Nodes’ display
optionSelect the nodes to remove from job group 27
Click ‘Remove from group’
Now raise job 27 priority to the top
The nodes which are in job group 27 will now start processing job 27
It is also possible to exclude a node completely so that it will not be given any work
Select a node and clickWhen excluded, the node will appear greyed out and stop any work it is currently doing
The removed nodes continue processing job 25

Node ManagementIf a node keeps failing tasks, it will be automatically excluded and blacklistedTo unblacklist and include a node, select it and click
The node will then automatically begin processing any available tasksNodes are marked as dead when disconnected for longer than 5 days (default)To delete disconnected and dead nodes, select the required nodes and click
