We're currently doing some minor maintenance on the storage file system.

The batch queues on Kebnekaise are stopped, therefor no new jobs will be allowed to start.

Already running jobs will continue to run.

The file system should be available most of the time but may at times access may be stalled for shorter periods.

Logins may be slower than normal.


* UPDATE 2020-12-01 11:30 *

Maintenance done and batch queues now running again.

We have a maintenance window starting 2020-11-12 08:00 for migrating to our new storage system.

This affects batch queues and login nodes for all users.


We have acquired a new storage system which will replace our old center storage.
The new storage is twice as large and will provide better performance overall for both user and project storage.

The old storage will be decommissioned and the data must therefore be migrated to the new system.

Name resolution outage 2020-10-10 (resolved)

Early Saturday morning on October 10th we observed an outage in name resolution (DNS) for HPC2N hosts.

This prevented external and internal access to batch nodes, the website and more.

2020-10-10 11:00
We have restored DNS functionality and HPC2N should once again be reachable from the outside. It may take a little while for the changes to propagate out to internet providers.

Batch jobs that were running may not have run to completion and any queued jobs may have failed on startup.

Short maintenance on parallel file system servers, 2020-06-23 08:00

We need to make a short maintenance on the paralle file system servers, 2020-06-23 08:00.

The operation should take approx 15-30 minutes.

There will be no jobs running during the maintenance since the operation is somewhat disruptive to the file systems.


Only jobs with a runtime that ends before the maintenance will be allowed to start.


Jobs with short runtimes will have a high likelyhood of getting run in the upcoming gaps.
