Problem with file permissions in certain projects
We have restored project access for some projects. Access was
temporarily lost due to a glitch in our system. PI of affected projects have been / will be contacted.

What happened? Yesterday, affected project directories unexpectedly got a new group id, without adding any users for that group id. The new group was then set as owner of several folders, meaning no user could access them.
Solution? We reset all group ownership to normal - its own group. That is usually the only expected group ownership in project folders. But if you had only yourself or another group as owner of files, it is now overwritten.
If there would still remain problems of getting access to files, just contact us at firstname.lastname@example.org and we will help you.
If you had set special group ownership for any files, you need to set them again, or ask us to do that.
We are sorry if this has caused any inconvenience for you.

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).
