There is also one other option, when you run the script with updatenode, we export an environment variable in the mypostscript file which your script can check. This will tell it, it is being run by updatenode vs during install. UPDATENODE=1 export UPDATENODE
So you will see checks in our postscripts like the following to run different logic whether it is being run by updatenode or during install. You could put this check at the start of the script and exit when run by updatenode. if [ -n "$UPDATENODE" ] && [ $UPDATENODE -eq 1 ]; then Lissa K.

Will fix that. Lissa K.

From: Craig West <[email protected]> To: xCAT Users Mailing list <[email protected]> Date: 01/02/2013 06:45 PM Subject: [xcat-user] Post BOOT scripts Hi, Trying to get an understanding of postscript versus postbootscripts. I understand that postbootscripts are run after the first boot, but it seems that they also get run every time updatenode <node> is run as well. I was hoping to use postbootscripts as a method for running scripts that only need to be run once after the machine is installed. Of course, they are still able to be run manually if I need them again. An example is configuring the Infiniband device. A script is provided called "configiba.1port", but putting it in postbootscripts and running updatenode makes that script get run again (each time the updatenode postscripts section is called). This script actually restarts the Infiniband stack, which has the potential to kill jobs and also causes Lustre issues (it hangs as Lustre is using the device and the script never completes). If this script was run once after boot only it wouldn't be an issue. For now we have modified the script to stop it restarting, but its not the best of solutions. Is this a bug, or a misunderstanding of the point of postbootscripts? The documentation I have found is not clear either way. Note: Running Centos 6, xCAT 2.7.6 and disk full installs.
