Abisko is down due to network problems.

We are investigating the problem.

All queues have been stopped.

*UPDATE 2016-03-09 19:18*
The main ethernet switch for Abisko has died.
We will chase our supplier to fix this asap.

It will not happen until earliest tomorrow (2016-03-10)

*UPDATE 2016-03-09 20:00*
We found a spare power module for the switch and Abiskos ethernet network is now back onlnie.
We will verify system functionality (see other system news about /pfs/nobackup) before bringing the batch queues back on.

/pfs/nobackup problems

We are currently experience some problems with the /pfs/nobackup filesystem. Investigations are ongoing. 

All the batch queues have been stopped until further notice.

UPDATE 13:04: Everything should be back to normal state again. It seems that it was only a local problem on the Abisko login node. Jobs running through the batchsystem should not have been affected.

Power maintenance 2015-09-18 06:30, batch nodes will be drained of running jobs.

The power company is doing a maintenance on the high voltage feed to the University on Friday September 18th, 06:30.

This will result in total power loss to the whole University, thus we need to drain the batch nodes.

During the days leading up to the maintenance window, it is advisable to submit shorter jobs, that can finish in the remaining time until the window starts. To allow a little bit of margin the system will not allow jobs to run after 06:20 on the 18th.

Batch queues stopped due to /pfs/nobackup being out of inodes (files). (Partially fixed)

We have unfortunately been forced to stop all batch queues on the clusters.

/pfs/nobackup has run out of inodes. Something probably created more inodes (files) then intended.

We are working on finding out where and getting the usage down to normal levels.

Until this is fixed we need to keep the batch queues stopped to avoid risking jobs to fail due to not being able to create new files.
