Server has no node list when executing pbsnodes -s

If you see this error "Server has no node list" when you execute "pbsnodes -s 192.168.1.1" (your torque server DNS or IP), it is due to the missing "nodes" file that was supposed to be at /var/spool/torque/server_priv/

The node file should show something like this

## This is the TORQUE server "nodes" file.
##
## To add a node, enter its hostname, optional processor count (np=),
## and optional feature names.
##
## Example:
##    host01 np=8 featureA featureB
##    host02 np=8 featureA featureB

compute-c01     np=12
compute-c02     np=12
