Because of an urgent configuration change on the following LRZ Data Science Storage file systems: /dss/dssfs01 /dss/dsstumfs01 /dss/dsstumfs02 on Monday 2019-02-11 between 06:30 to 07:00 o'clock, we have to perform a restart of these systems. Therefore the filesystems will be unavailable for about 10-15 minutes during this timeframe. We apologise for any inconvenience on your side and try to keep the offline maintenance window as small as possible Best Regards, LRZ ISP Team
