File server’s OS update

Update (26.10.2018, 16:22 EEST): The OS update of the file server has been completed. The workload manager queues are reinstated and you may now submit jobs again. Thank you for the consideration.

Dear users,

This Friday (26.10.18) we will be pushing an OS updated on Nestum’s file server. Due to the update, the machine will be unavailable between 10:00 and 22:00 EEST (Bulgarian Time). Furthermore, the long.p partition in Slurm is to be switched offline in order to prevent data loss on the day of the update. We apologize for the inconvenience.

Emergency shutdown

Due to an unexpected aggregate load, Nestum was switched offline this morning (around 10 AM local time). Although no data or job progress was lost, the machine will operate on reduced capacity until we are sure that the issue is resolved.

We apologize for the inconvenience.

Partitions back online

The “medium” and “long” partitions are back online, and you can submit jobs onto them. Unfortunately, a problem was detected on compute node cn014 and we’ve removed it from the queue until the situation is resolved.
