Revision as of 07:48, 2 October 2017
CSCS informed us that the data centre will be undergoing maintenance on Wednesday 27 and Thursday 28 September 2017, which will require a complete shutdown of Euler.
We will take this opportunity to do some additional maintenance on Euler itself the days before and after the CSCS maintenance. In particular, we will complete the upgrade of Euler to CentOS 7 and prepare for the installation of Euler IV later this year. The network at CSCS will also be updated on this occasion.
As a consequence we plan that:
- Euler compute nodes, login nodes, and storage systems will be off-line from 09:00, Tuesday 26 until the evening of Friday 29 September; we will do our best to bring them back on-line ASAP.
- Batch queues will remain inactive throughout the weekend until Monday 2 October 2017.
As usual, batch queues will be progressively inactivated in the days and hours prior to the maintenance, to ensure that no jobs get killed when the cluster is shut down.
Sorry for the inconvenience.
