A node enters the "maintenance" state when the first job is suspended with the new suspend signal. If other jobs are running on a node in the 'maintenance' state, they will continue to run until they are subsequently suspended(or they end). The node will leave the 'maintenance' state when the last job is resumed with the new resume pseudo signal. The scheduler will not run new jobs on a node in this state. It will also not resume any suspended jobs that were suspended via the 'suspend' pseudo signal or preemptionin the suspended state.
