Due to an open security issue we have deactivated user namespaces on all Rocky 9 systems. This feature is mainly used by containerization software and affects the way apptainer containers will behave. Most users should not experience any interruptions. If you experience any problems, please contact us as usual via servicedesk@itc.rwth-aachen.de with a precise description of the features you are using.
The user namespaces can be activated again once the Rocky 9 nodes are upgraded to Rocky 9.6. The dialog systems (cf. other ticket) were upgraded already. Currently we are procuring the upgrade to Rocky 9.6 in the background to minimize the downtime. Already upgraded nodes have user namespaces enabled by default again.
The remaining Rocky 9.5 nodes are planned to be updated to Rocky Linux 9.6 until 2025-07-04
Due to high-risk security issues within some components, the affected packages had to be removed from the cluster to enable operation until the security issues can be fixed. Unfortunately, the removal breaks the desktop environments XFCE and Mate due to tight dependencies to the respective removed packages. Consequently, the file managers "Thunar" and "Caja" as well as some other utilities cannot be used at the moment when using a GUI login. If a GUI login is mandatory, please use the IceWM environment instead. However, some of the GUI applications might not work as expected (see above). The text-based/terminal usage of the frontend nodes is not affected by the temporal change.
The upgraded Rocky 9 login nodes have received patches that solve the security issues. On these nodes, Mate and XFCE can be used again as desktop environment. However, The Rocky 8 login nodes (i.e., login23-3, login23-x-1) are still awaiting the respecitve patches. Until the patches are available, the usage of the respective environments remains limited.

The HPC JupyterHub will be down for maintenance during the hours of 9:00 and 11:00.
On Monday, June 23rd, the CLAIX-2023 Rocky 9 frontend nodes login23-1, login23-2 and login23-4 will be upgraded to Rocky Linux 9.6. During the upgrade, these nodes will temporarily not be available. Please use the Rocky 8 frontend nodes in the meantime.
login23-g-1 and login23-x-2 will be reinstalled with Rocky Linux 9.6. Until the reinstallation is finished, these nodes are temporarily unavailable.
The GPU login node login23-g-1 is reinstalled and available with Rocky 9.6. The other nodes require further work.
The login nodes login23-1, login23-2, login23-4 are updated and available again. login23-x-2 requires some further work.
All Rocky 9-login nodes are upgraded to Rocky Linux 9.6.
