On Sep 4th 08:00 CEST we will have a maintenance window to change some parameters for the lustre file system.
To be able to do this we need to empty the clusters from running jobs and reboot all nodes including the login nodes.
As we get closer to that point in time, jobs will not be allowed to start if their requested runtime is too long to fit before 2017-09-04 08:00.
In other words, submitting jobs with shorter runtimes will be a good idea.
