Dear IANVS users,
the cluster is back online. There has been no data loss on the /home or /scratch partitions.
The issue happened because today, on 2025-01-30 08:30, an error during repairs to the ITZ’s power infrastructure led to a voltage spike on one of our two power lanes. The ITZ’s systems have redundant power supplies and were mostly not affected. While IANVS has redundant power supplies as well, the outage has resulted in power loss nearly half of all systems. This took down the distributed file system, which in turn took down the resource scheduler and the job queue.
All systems have now been put back online.
Please contact us if you have any questions: via e-mail or phone, (0345) 55-21864.
Best regards,
ITZ HPC Team
