On Tuesday August 16 between 06:00 and 06:30 local time there will be a complete power outage on the Umeå University Campus due to revision of the high voltage supply system.
All clusters will be offline during the outage, with some margins before and after.

On June 14th maintenance on the electrical feed to our cluster computer room will be performed.
We estimate this to start at 09:00 on June 14th and be finished during the afternoon.
Akka and Ritsem will be turned off completely during this maintenance window. Jobs that have a walltime extending into the above time frame will not be allowed to start. This means that during the days leading up to the time frame Akka will seemingly have free nodes available but jobs will will not start.
We apologize for any inconvenience this may cause.
Akka and Ritsem are now back in production efter the maintenance.
There are still some upgrades in progress on the batch nodes of Akka which will cause gaps in the batch system.
We will work as fast as possible to finish these upgrades.

During May 2nd to 10th there will be an electrical maintenance in one of
our computer rooms.
This is due to an upgrade of the electrical facilities to accommodate our
new cluster.
Akka, Ritsem and Sarek will be turned off completely, including login
nodes, during the whole period. Jobs that have a walltime extending into
the above time frame will not be allowed to start.
This means that during the days leading up to the time frame Akka will
seemingly have free nodes available but jobs will will not start.
The problems in the batch-system have been fixed and it works normally again.

We are currently experiencing some problems with the batch system.
We are working on getting it back in working order.

We had an power outage affecting Akka and Ritsem around 14.30. All jobs running on Akka and Ritsem were lost.
We are working on getting everything up and running again.

Home directories can again be accessed normally.
We do not expect any further issues in relation to this, but if you still have problems, please contact support@hpc2n.umu.se.

We are currently experiencing transient problems with access to the home directories located in our AFS. This is due to restart of the AFS server. We expect to be back in service within a couple of hours.

Sarek is blocked from starting new jobs due to a problem with the cooling system that will need an emergency repair.
(This does NOT affect Akka which is located in a different room.)
