system news

The batch master server for Abisko needs hardware maintenance and the /pfs/nobackup file system needs a reconfiguration.

We will begin this on Wednesday Jan 21th, starting at 08:00 CET. Unfurtunately the /pfs/nobackup maintenace took longer than expected, so we're still working on this on Thursday Jan 22.

A reservation has been put inplace on the batch systems which means that jobs will not be started unless they are short enough to finish before that time.

The login nodes of both clusters will also be disabled.

During the Christmas holidays we are running with reduced staffing.

We will try to solve any arising problems as quickly as possible, but there will be delays due to this.

We will be back at full capacity on Jan 7th.

We had some raid problems on our batch server, meaning (among other things) that no jobs could be submitted. 

It was necessary to reboot to server. Everything seems to be working correctly again.

We have some disk problems on our batch server.  This means that no jobs can be submitted. We are hoping it will not affect running jobs.

Friday afternoon (around 14:30) we had a power outage which affected both our cluster (Abisko and Akka). Our power company is blaming the weather.

Power should be back now and we are in the process of restarting everything.

The new centre storage is now in production.

The /pfs/nobackup file system is now larger and faster, ... finally.

Almost all users have been synchronized to new new file system.
The few remaining users (those affected will get a separate mail) have been blocked from logging in and their jobs put on hold until the transfer is complete for each user.

Jobs are running again and login has been opened (see exception above).

If you notice anything strange please notify support@hpc2n.umu.se.

On Tuesday October 14 06:30-13:00 the HPC2N compute resources will be unavailable due to maintenance work being performed on the cooling/ventilation system in the cluster machine room.

Note that jobs that would extend into this downtime window won't start until the downtime has passed.

Due to a recent security update of the 'bash' shell there is a high probability that jobs that were submitted before the nodes received the update may fail to use the 'module' functionality once they start running.

As the login nodes are now updated, any future job submissions should work as intended as soon as you log out and in again of any long-running sessions, as you need to be on the new version of the shell.

We are very sorry about this unforeseen problem.

On Tuesday (2014-09-16) we will start to do more large scale tests of our new center storage.

We have made a reservation of the system between Tuesday and Thursday for this.

Abisko will therefor be drained of jobs during this time.
