Downtime due to power outage
Milou, Tintin, and Fysast-1 are back in production. Bianca is back in test production. Still working on Smog.
There was a power outage this morning. Our systems at UPPMAX were affected by this. We are investigating the extent, to see what systems are affected, and if any permanent damage was done. All our efforts are focused on getting all clusters back up again.
There is a problem accessing several volumes on Pica. We are in contact with the manufacturer. Until Pica is available, compute nodes are drained on Tintin, Milou and Fysast1, meaning no new jobs can start. Login nodes are up, but home directories are unavailable.
Most of Irma is in production. Some compute nodes need further investigation.
Bianca is not yet in production. We need to power up storage system Castor first (it was shut down to stop the rapid warming of our computer room). This will probably be done in the afternoon.
Pica is alive and well. Milou, Tintin, and Fysast1 are back in production.
We are still working on Bianca.
Still working on Bianca and Smog. We are expecting Bianca to be up later today.
Biance is back in test production, which means test projects on Bianca can run just as before.
Bianca's storage system Castor had a hiccup yesterday Thursday -- FIXED
Maintenance window Wednesday 2017-08-02 -- FINISHED
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
No maintenance planned for today's maintenance window
First (non-holiday) Wednesday of each month is UPPMAX's normal, planned maintenance window.
But today we will do no maintenance.
Next maintenance window is 2nd of August.
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.
UPDATE 16:00 - Update completed.
