We experienced a few hours of unavailability on parts of the cluster between late wednesday 6th January and early afternoon on 7th January.
We are currently planning to upgrade Idun cluster into a newer Centos version, and in the preparation we need to change internal IP addresses of all nodes (including login nodes). As part of this work we made a configuration error which caused some nodes to have wrong ip address config.
We will send out an update later this month about possible, planned, downtime for the transistion to an upgraded Centos version.
In other news: The IT department has expanded their share with 8 new compute nodes. This means that there are more "free" cpu hours available in addition to the individual stakeholders shares. We are expecting new shareholders shortly also.
