Abisko will be down due to maintenance on the cooling system 20160413 and 20160414.

During that time we will also perform some maintenance on the /pfs/nobackup file system.

This means that /pfs/nobackup will be unavailable both of those days.

No jobs will be allowed to run during this maintenance window.

*UPDATE 2016-04-14 19:00*
The system is now back online again.

Abisko is now back online after a two day maintenance window.

We have found some discrepancies regarding the quota information that are not yet fixed.

Some users have large differences between what the quota system thinks and what is actually there in the file system. This may cause some problems with hitting the file quota limit. If this happens please send a mail to support@hpc2n.umu.se and we will deal with it.

We will try to fix this problem during the next maintenance window in May.

For unclear reasons, accesses to AFS on the abisko login node just hung. With no way to fix it, we choose to reboot it.
