The investigation results that followed the system failures that temporarily rendered the scientific repository unresponsive (http://blog.pace.gatech.edu/?p=6390) will require some additional maintenance. To facilitate this maintenance, we will make a change to the mount point for /usr/local, which is network mounted and identical on all compute nodes.
Our tests indicate that this swap can be performed live, without impacting running jobs. It’s also completely transparent to users; you don’t need to change or do anything as a result.
In the unlikely event of job crashes that you suspect are caused by this operation, please contact pace-support@oit.gatech.edu and we’ll be happy to assist.
Thank you,
PACE Team
