Colossus maintenance on Monday, 30th September

UPDATE: Unfortunately, we encountered some unforeseen problems, and were not able to switch to the new NFS-exporter today. The system is now back in normal production using the old exporter, and you can continue to work as normal again. We hope to solve the problems quickly, and come back with a new day soon for replacing the NFS-exporter.

We are sorry for the inconveniency.

We will replace the existing NFS-exporter on Colossus starting on Monday, 30th September 09:00 CET, and continue working throughout the day.

We will stop the NFS-export by dismounting it on all Virtual Machines, and some may also require a reboot.

You will not be able to run jobs on VMs that need data from /cluster or software modules. If we have to reboot the VM to unmount /cluster, the running jobs will also be killed.

Please save your data before the maintenance window, and follow our Operational Log for the update.

The upgrade may be completed earlier, and in that case, we will update the progress, here: http://www.uio.no/english/services/it/research/sensitive-data/log/

This work will increase the current bandwidth to export /cluster partition to the HPC-projects, which has a been a problem lately.
