we are experience in the moment a serious problem in our GPFS infrastructure.
We are in the process to analyze which parts are involved and can't therefore can't give now any further details.
At the moment the maxwell home directories are not available so you can't login to the maxwell login nodes. The software folder is also not accessible.
The beegfs is not involved so it is clear that it is not the infiniband network.
As soon as we get new information we will update this post
