Short maintenance on parallel file system servers, 2020-06-23 08:00

We need to make a short maintenance on the paralle file system servers, 2020-06-23 08:00.

The operation should take approx 15-30 minutes.

There will be no jobs running during the maintenance since the operation is somewhat disruptive to the file systems.

 

Only jobs with a runtime that ends before the maintenance will be allowed to start.

 

Jobs with short runtimes will have a high likelyhood of getting run in the upcoming gaps.

Power is now back and we are powering up the systems

*UPDATE 20200527 11:50*

Login nodes are now open again, cluster batch nodes are coming up soon and jobs will start running before 13:00

Monday 2020-05-11 we will have a maintenance on the cooling system.

This affects both clusters causing them to be offline.

The maintenance window is between 06:00 and 17:00 on Monday 2020-05-11

During the time leasding up to the downtime only shorter (and shorter) jobs can run.

 

*UPDATE 2020-05-11 17:35*

An unexpected problem is causing a delay in getting the clusters up and running again.

We're working as fast as we can to fix the problem.
