Akka has served us well for eight years but will now finally be retired.
Akka will be turned off at the end of March and dismantled to make room for our new upcoming system.
The /pfs/nobackup filesystem has stopped responding.
*UPDATE 2015-12-16 18:10*
The file system is now back online again and the queues are running.

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.

Thursday (and possibly Friday) 2015-10-15 (and 16) we will do some maintenance on the Akka system.
No batch jobs will be running during the operation.
The login node will also be turned off.

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.
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.
The /pfs/nobackup (lustre) file system is currently unavailable due to after effects of an electric maintenance problem (see here).
We apologize for any inconvenience this may cause.
We are currently working on restoring access to pfs, but we do not have an ETA right now.
This news will be updated with more information when we have it.
*UPDATE 20150820 15:45*
It will, most likely, take at least until Friday 21th, before we can get this resolved.
The filesystem is now back in production.
As far as we can tell no files or directories where lost, but if you do find evidence of that, please notify support@hpc2n.umu.se, so we can report it to the vendor.
We're sorry about the long downtime, but we were verifying each step with the vendor, to do our best not to loose any data.
