3.3 Changing Node State
A common task is to prevent jobs from running on a particular node by marking it offline with pbsnodes -o nodename. Once a node has been marked offline, the scheduler will no longer consider it available for new jobs. Simply use pbsnodes -c nodename when the node is returned to service.Also useful is pbsnodes -l which lists all nodes with an “interesting” state such as “down”, “unknown” or “offline.” This provides a quick glance at nodes that migth be having a problem.
See the pbsnodes manpage for details.
