Maintenance on Lustre affecting both Kebnekaise and Abisko on 2017-04-19, 2017-04-20

On Wednesday April 19th we have a maintenance window from 08:00 to 21:00 to change some Lustre configuration and update Slurm on Abisko.

This affects the /pfs/nobackup filesystem on all batch and login nodes on both Kebnekaise and Abisko.

We must therefore drain the batch nodes of jobs. This means that there will be gaps which can be filled by short jobs during the days before the 19th.

Please do submit short jobs to fill those gaps.

We will also update the batch system on Abisko (Slurm) in preparation for the upgrade of Abisko to Xenial. This involves a number of updates to the database and will thus take quite some time.

The maintenance window will prevent any pending jobs from starting until we are finished and the window is removed.

* UPDATE 2017-04-19 22:55 *

Due to unforseen problems with the new Lustre configuration the system remains in maintenance mode.

We need assistance from our supplier of the file system and will continue in the morning.

* UPDATE 2017-04-20 12:50 *

Kebnekaise is now back online.

Abisko will take a while longer.
