The Leonhard Open Lustre filesystem on which /cluster/work and /cluster/scratch reside needs to be restarted.

This operation is planned for the morning of Monday, March 18 2019.

Since we expect the reconfiguration to be minimally intrusive, the cluster will be kept online during this time. However, to minimize the impact of any potential issues we will ensure that no new jobs will start the day before, leaving only existing jobs in the 120h queues running.

Update 18 March. 2019, 10:20:

The restart has been completed. Queued jobs can again run on the cluster.
