*** 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,

Kebnekaise and Cluster maintenance at HPC2N 2021-11-15 06:00 - 2021-11-17 17:00

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.

Problems with project storage (2021-06-11) *SOLVED 2021-06-12 01:17*

Problems with project storage, mkdir fails and new directories cannot be created

The exact cause is not known but we are doing active debugging together with our vendor. During the debugging we have blocked the starting of new batch jobs. You can still submit jobs but they will not start until the problem is solved.

 

* SOLVED 2021-06-12 01:17 *

The problem was finially identified and a workaround put in place.

The system is now back in production.

Minor upgrade to $HOME and project storage file servers 2021-05-26 - FINISHED

During the period 2021-05-26 - 27 we will be doing a minor upgrade to the file servers for $HOME and the project storage.

The upgrade will be done in two stages to avoid requiring a full downtime.

There will be an initial shorter service interrupt Wednesday around lunch, followed by reduced performance.

There will then be another slightly longer service interrupt followed by another period of reduced performance.

When the second interrupt occurs depends on how fast the first stage of the upgrade goes.

 

Upgrade to Ubuntu Focal on clusters starting 2021-04-19 *UPDATED 2021-04-27, DONE*

Since the current operating system version, Ubuntu Xenial 16.04, that we are running on our clusters is reaching its End-Of-Life on 2021-04-30, we are upgrading to Ubuntu Focal 20.04.

The upgrade process will start 2021-04-19 and will be done with minimal impact to users running jobs.

Access to user data will not be affected by this upgrade.

There is already now a test environment available for users to check this out.

It is imperative that users test this out as soon as possible and notify us of any missing softwares.
