Queues defined above do not work until you start them:
qstart default small medium long verylong
qenable default small medium long verylong
This needs to be done only once and for all, at the time when you install PBS.
Make sure that the PBS server has all nodes correctly defined. Use the pbsnodes -a command to list all nodes.
Add nodes using the qmgr command:
# qmgr
Max open servers: 4
Qmgr: create node node99 properties=ev67
where the node-name is node99 with the properties=ev67. Alternatively, you may simply list the nodes in the file /var/spool/PBS/server_priv/nodes:
server:ts ev67
node99 ev67
The :ts indicates a time-shared node; nodes without :ts are cluster nodes where batch jobs may execute. The second column lists the properties that you associate with the node. Restart the pbs_server after editing manually the nodes file.
After you first setup your system, to get the jobs to actually run you need to set the server scheduling attribute to true. This will normally be done for you at boot time (see point 5 in this file), but for this first time, you will need to do this by hand using the qmgr command:
# qmgr
Max open servers: 4
Qmgr: set server scheduling=true
