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.

Akka has served us well for eight years but will now finally be retired.

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.
