Maintenance window Wednesday 2016-12-07 -- FINISHED
Monthly maintenance window begins at 0900 hours.
This time we will:
- Upgrade kernel and other system software on all nodes of Fysast1, Irma, Milou, Tintin, and Smog
- Restart Lupus
Slurm queues are stopped on Irma, but not on the other systems. We expect to finish sometime during Wednesday afternoon.
Login nodes will be rebooted once during the day (we will warn logged in users an hour in advance).
During the maintenance day, we will now and then update you about our progress, within this web page.
Update at 13:30
Upgrades are done on Milou and Tintin. This means all running jobs will finish, then the nodes will be restarted and updated before new jobs are started. No jobs are interrupted, but there might be a slower queue the coming week.
Update at 18:00
Most parts of our filesystem checks on Lupus is done. We'll working on getting Irma back in production, this evening or tomorrow.
Update December 8, 14:00
What was planned to do for the service window is completed for Irma and Lupus and queues for Irma are open again.
Singularity is available

Issues with X11 on milou (X11Forwarding) -- SOLVED
We have observed and several users have reported issues with running X11 applications on Milou. We are investigating it.
milou2 and milou-b rebooted
The login nodes milou2.uppmax.uu.se and milou-b.uppmax.uu.se were rebooted 15:00 today (29th of May) due to some issues with the kernel NFS module.
Cooling stop at 17.00 hours the 23rd of May -- CANCELLED
Issues with certain project volumes for milou/pica 20170515 and onwards.
Some project volumes on pica are very heavily loaded and slow/next to unusable for interactive use. We're doing what we can to resolve this but can not promise any set time for when things will behave as normal again.
UPDATE: We've had some continuing issues with this due to some nodes not realizing when resources behave better, we're working on these issues but this may have caused disturbances like failed jobs or missing output.
Support may be slow May 11th and 12th due to conference
The UPPMAX system group hosts the spring 'SONC' conference where administrators from all SNIC-centers meet and discuss how to improve our centers. With many UPPMAX adminstrators being out of office during the conference (Thursday 11th and Friday 12th) the support will likely be less responsive.
slurm disturbance on milou 2017-05-10
Due to a misconfiguration active on a certain number of nodes around 12AM today, some jobs that were launched on milou could not start.
If you have jobs that were victims of this, they will likely show up as completed although with a very short run time (a few seconds).
