The /pfs/nobackup is currently down, we are working on fixing it.
This system news will be updated.

/pfs/nobackup is working again and the batch queues are running again.
A page for our new cluster "Kebnekaise" has been created. Not much information there yet, but more will follow soon.
The cluster is not yet open for use.
On September 6th between 08:00 and 17:00 we will perform some necessary software updates of the servers that deliver the /pfs/nobackup file system.
This means that the batch nodes of Abisko must be drained of jobs and the file system unmounted on all nodes, including the login node.
During days leading up to the maintenance window, the system will only accept to run shorter and shorter jobs. It is therefore benficial to submit jobs with short runtimes.
We have a maintenance window on Abisko on Thursday 2016-08-11 between 08:00 and 11:00.
We need to do some disruptive operations on the infiniband network.
We are experiencing some problems with one of the AFS-servers. We are working on it and hopefully it should be back online soon.
As a security measurment we have stopped the batch queue (no new jobs will start). The queue will be restored as soon as the AFS server is back online.
AFS has been back online for a couple of days.
We apologize for not updating the status!
The batch nodes of Abisko is currently down due to a major power failure in Umeå.
The lightning looks to have caused a short-circuit in one of the circuit breakers feeding Abisko.
(To give the electricans a better chance to solve the problem, all power feeds are kept off for the time being, so Abisko is currently completely without power.)
We are currently waiting for electricians to arrive on site.
We are experiencing some problem with /pfs. We are working on it and hope to get it back online soon.
During this problem we have stopped the batch queue (no new jobs will start). As soon as pfs is back we will start up the queue again.
*UPDATE 2016-05-09 16:30*
Pfs back online. Batch queue started again.

Our long awaited upgrade of the Lustre file system to double the size and performance is finally approaching.
On May 2:nd (2016-05-02) Abisko will be down (no jobs running) and the login node will be taken offline.
This is necessary to be able to add the new hardware and do the required recabling/rearranging of the system.
The down time will be at least two days long.
