Helvetios: Back to production in degraded state!
The Helvetios cluster is now available again, but in a reduced and isolated configuration. Please read carefully the key changes and actions required.
Current Status
- The cluster is back online with only 24 nodes currently provisioned.
- Helvetios is no longer connected to the central storage, meaning:
- /home, /scratch, and /work are now local to the cluster
- The /work filesystem is no longer shared
- All data previously stored in /scratch has been lost and cannot be recovered.
We plan to gradually increase the number of available nodes as soon as we confirm system stability.
Why These Changes?
- Helvetios is based on unsupported, obsolete hardware, and SCITAS can only provide best-effort support for its maintenance.
- Recent network issues on Helvetios have caused disruptions and performance degradation across all production clusters by impacting the central storage.
- To protect the integrity of the production environment, we had to isolate Helvetios from shared storage.
What You Need to Do
- Manually copy your SSH keys
- Data previously stored in /home or /work (when it was part of the central storage) will need to be restored manually.
We understand this situation may cause inconvenience, and we appreciate your patience as we continue to maintain access to this legacy system under challenging conditions.
Happy computing! 😊🚀
