Unexpected reboot of Pica at Monday morning.
Restart of two Milou login servers today Thursday
Lower service level during UPPMAX holidays
Part of storage system Pica is still very slow
Pica was partly restarted just now, please look for problems in your job output
UPPMAX had to restart part of storage system Pica, because it worked too slowly with nearly no read/write traffic.
The restart was done a little after 1300 hours.
For Rackham users, this meant that you might have had problems with reading and writing to your home directory.
For Milou users, this meant that you also might have had problems with reading and writing to your home directory. But for Milou users, also reading from /sw (where the modules live) and reading and writing to some project directories were affected.
Please look one extra time for problems in your job output, for jobs running at this time.
We are sorry for the inconvenience.
On Milou and Rackham, very difficult to login or otherwise use /home directories -- FIXED
UPPMAX has problem with an extremely slow access to /sw (where e.g. modules live) and home directories on Milou, and to home directories on Rackham.
Because of that, it is very difficult to login to Milou and Rackham.
We will investigate the source of this problem, and will report any success as updates here.
Update at 1310 hours
We restarted part of Pica, and that solved the problem
Hopefully your jobs will continue without problems, but please be careful and look once extra time for errors in your job output.
SUPR and C3SE website down
SUPR and C3SE websites are down at the moment. This prevents you from using SUPR at the moment. Please try again later

Restart of login server milou-f Tuesday morning -- FINISHED
File system mounts of Pica volumes was not working correctly.
This was fixed by a restart of the server. Now it works much better.
We are sorry about any inconvenience for you due to this.
Lost contact with Milou nodes m[1-48] for an hour this morning -- FIXED
From approximately 0800 hours to 0910 hours this morning, an ethernet switch in Milou lost power, making 48 nodes unavailable.
Two jobs got NODE_FAIL when trying to start, and interactive work on these nodes was denied. Otherwise, we seem to have had no problems with the temporary network loss.
Singularity is available
Urgent kernel upgrade -- FINISHED
Today we are performing an urgent kernel upgrade on Milou, Fysast1, Rackham, Irma, and Bianca. Login nodes will be restarted during the day. No running jorbs or queues are stopped. We will update on the progress here in System News during the day.
