No new logins are possible during the maintenance work. Users who are already logged in will not be disturbed and the maintenance will not affect the rest of the cluster. All frontends are still available, as is the batch system with its computing nodes.
The installation of HPCJupyterHub Profiles is currently unavailable due to issues with our HPC container system. A downtime of at least two weeks is expected. We apologize for the inconvenience.
The CLAIX-2023 login node login23-4 will be upgraded to Rocky Linux 9.5 for assisting the migration to Rocky Linux 9. During the version upgrade, the login node will not be available.
The CLAIX-2023 dialog node login23-4 is currently unavalable due to testing with respect to the planned migration to Rocky Linux 9. Please use an other dialog node until access to this node is available again.
At the moment, some issues with the file systems that impact the performance are observed. File access can be severely delayed consequently. The issue is currently under investigation.
We were not able to identify the root cause of the observed issues and are still working on a solution.
We changed some network settings on the GPFS servers, but that did not change anything. We are still working with the manufacturer to get a solution.
Additional changes have been made to the configuration. Initial tests tend to show an improvement in the GPFS performance. A full qualitative analysis of the performance is pending
The performance of the HOME and WORK filesystems are much better now.
Due to maintenance tasks on a cluster-wide scale that cannot be performed online, the whole batch service will be suspended for the maintenance. The Regapp is also affected by the maintenance.
The infrastructure of the HOME and WORK filesystems will also be under maintenance. Hence, the frontend nodes will be inacessible as well until the pending tasks are completed.
Due to delays in servicing the file systems, the cluster maintenance needs to be prolonged.
Due to delays in deploying the updated file system, the maintenance hat do be prolonged.
Due to a scheduled kernel update, the jupyterhub node is temporarily unavailable. The node will be available again, as soon as the update is completed.
