How can I get Torque to recognize additional memory added to a node?


Issue:  Torque caches a lot of node information, including memory.  After adding memory to a node, the server may not see that additional memory.

Solution:  There is a fairly simple process, requiring restarting of pbs_server twice, which will cause Torque to update it's node configuration.  These steps are:

  1. Shut down the pbs_server
  2. Remove the node(s) with additional memory from the "nodes" file (/var/spool/torque/server_priv/nodes, by default).
  3. "cd" to the /var/spool/torque/server_priv/node_usage directory and remove the file(s) whose name(s) correspond to the node(s) with new memory
  4. Start the pbs_server. 
  5. Add the node(s) BACK into the "nodes" file.
  6. Restart the pbs_server. 

After that second restart, Torque's view of the total memory for the node(s) should be correct.
