[torqueusers] Is that possible to run two pbs_server daemons for the same cluster for fall-over purpose?

Yang,

   The developers can answer your original question, but I'm 
guessing you cannot.  Because trying to start a second server gives
you the message:

pbs_server: another server running

    What I do instead is have a cron script run the following script 
once each hour on my head node: (I used to run this every 15 minutes)

#!/bin/ksh

PS_PBS_SCHED=`/bin/ps -aef | grep pbs_sched | grep -v grep`
if [ -z "$PS_PBS_SCHED" ] ; then
  /usr/local/sbin/pbs_sched
fi

PS_PBS_SERVER=`/bin/ps -aef | grep pbs_server | grep -v grep`
if [ -z "$PS_PBS_SERVER" ] ; then
  /usr/local/sbin/pbs_server
fi


I have a similar script for pbs_mom on the compute nodes.
