system news

On Monday 2022-06-27 we will start an upgrade of the file system servers.

Our hope is that this will reduce the amount of problems we have had the past couple of weeks.

The reason for the rather long maintenance window is that we will do some cleanup of potential and known problems before the upgrade and that is expected to take a relatively long time.

Further information on progress etc will be updated on this page.
 

*UPDATE 2022-06-29 11:00*

The upgrade of the server code is done and initial file system checks have finished.

SOLVED 2022-06-08 18:00

The problem is resolved and the system should be up and running normally now

Follow-up Cooling maintenance computer hall, cluster down 2022-04-05 13:00

We plan to have the cluster up again later this evening around 19.00

*** UPDATE 16.00 ***

Kebnekaise is back up again and everything is back to normal

The cooling has failed in the computer hall causing an emergency power break.

We're investigating the reason and will try to get the cluster back as soon as possible.

* UPDATE 2022-04-04 16:30 *

The cluster is being brought up, this will take a while longer.

But  more cooling-related work needs to be done tomorrow, so we have put a reservation on the cluster starting 2022-04-05 13:00.

This means that only short jobs will be allowed to start until after the next cooling work is finished and the system is safe to bring up fully.

----------------------------------

Update 2022-03-25 12:20 Maintenance ended and Kebenkaise is up and running again and the accessnodes are also open

----------------------------------

Updated 2022-03-25 07:10 We have done most of the work and the current plan is that Kebnekaise will be up after 12.00 today

----------------------------------

On Thursday 2022-03-24 from 05.00 there will be maintenance on the cooling system for the cluster compute datacenter.

At the same time we will also do maintenance on the parallel file system.

*** UPDATE 2022-02-24 11:20 ***
The problem with the storage system have been solved and the access nodes are available again and the file system works as normal.

Some jobs might have been aborted due to the long delay in the storage system and will need to be restarted by the users one more time,
