system news

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,

*** UPDATE 2022-02-24 12:30 ***

Dear users,

During this maintenance, 2021-11-15 06:00 - 2021-11-17 17:00, we’re going to do some upgrades on the parallel file system, where home directories and project storage is located, along with other upgrades on Kebnekaise itself.

Since this maintenance affects the parallel file system we have to drain the batch nodes from running jobs. Login sessions will be disabled and active sessions will be terminated, during that period.

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

We are working with resolving the problem in contact with our vendor, we will post updates here when we have more information

UPDATED 15:15 Issues now solved, system is now working normally again

The thinlinc server at HPC2N is being upgraded and it is currently not available for service.

We should be finished before 2021-10-05 14:00

*UPDATE 2021-10-05 09:25*

Upgrade is done, if you notice any problems using thinlinc, try ticking the "End existing session" box in the thinlinc connection window.
