Kebnekaise maintenance window, 2026-09-22 - 25, *DONE*

We have a maintenance window on Kebnekaise 2026-09-22 - 25.

We will upgrade the batch system and the batch server.

The update requires updates to the database in two separate steps and will thus take quite a long time.

All accesses to Kebnekaise will be unavailable during this maintenance window, no batch jobs running, no logins available, including the OpenOnDemand portal.

Follow this page for progress information.

*UPDATE 2026-09-24 11:30*

We are now mostly done.

Login access to kebnekaise.hpc2n.umu.se is open.

Batch system is still under a maintenance reservation so no jobs will get started yet.

Thinlinc and OpenOnDemand access are still down since we are reinstalling those nodes.

We hope to be completely done later today.

*UPDATE 2026-09-25 11:00*

Batch jobs has been running since yesterday evening, if you notice any problems please let us know (use the SUPR support function).

Thinlinc access to kebnekaise-tl.hpc2n.umu.se is now open again.

OpenOnDemand is still being upgraded and won't be available until later (no ETA as of yet)

*UPDATE 2026-09-25 14:00*
Everything now seems to be working.

Batch jobs running, login access, thinlinc access and OpenOnDemand portal
