We are currently experiencing degraded performance for the Betzy file system. We are investigating together with vendor to find the culprit for this issue
[UPDATE, 2021-06-08 08:00] Betzy is now up and in production again.
[UPDATE] Unfortunately, the downtime is taking longer than anticipated, and will not be finished tonight. We plan on getting Betzy up again at around 08:00 tomorrow morning.
Campusservice at NTNU will conduct maintenance on the High Voltage circuits for Non-redundant power on 7th of June 2021, between 15:00 and 20:00. All compute nodes and login nodes will be shut down during this time, and no jobs will be running during this period. Submitted jobs estimated to run into the downtime reservation will be held in queue.
We have identified a hardware issue with login-2.betzy.sigma2.com
This means there is reduced capacity on betzy login nodes until further notice.
This will probably not be fixed until after Easter.
The Saga maintenance is finished and you are welcome to start computing again. We have added considerable amount of storage. In the following weeks we will reorganize the placement of some data to utilize the new disks. We were not able to add all of the expansion due to some hardware errors, but this will be added later.

Dear Saga user. We need to schedule a small downtime of Saga from Thursday 18th February 2021 starting at 08:00, until Friday 19th February 2021, ending at 16:00. If maintenance is finished earlier, we will also open up the machine earlier.
During the maintenance, we will continue the work we started in early december and connect the new storage expansion to the system, and make it available for general use. This will give us several Petabyte extra for project storage and other usage..
We apologize for the inconvenience
Update: The file system servers have now been fixed, and we are back online again. Thank you for your patience.
We have an ongoing performance issue with Fram filesystem. We need to shut down file servers to get this fixed, and therefore need to have three hours downtime:
Wednesday 20th January between 12:00 and 15:00, Fram will be unavailable
As previously announced, Saga will be down in the coming week, from 7th December 08:00 until 11th December 16:00.
The downtime is allocated for expanding the storage. When we come back we will have ca 4 Petabyte in addition to the already existing 1 PetaByte.
Update: Saga is back online and running jobs again. The new storage is not online yet, but all the hardware has been mounted.
As Betzy now has started production, the time has come to stop production on Vilje. On 1st of December no more jobs will be accepted into the queueing system and running jobs will be terminated. During the next few days after 1st December, the /work file system will be shut down and disconnected. ALL DATA on /work will be lost if you do not take proper measures and make sure you copy data out of Vilje before 1st of December.
We will try to have the /home filesystem still operational after 1st of december, but there is no guarantee this will be possible. There is also still a small possibility that Vilje could be available for running jobs after 1st of December, although highly unlikely.
On behalf of all previous and present NTNU staff:
Thanks for all the computing
We are going to expand the storage on Saga. This will happen during week 50, between 7th and 11th December. Hopefully this will give oss a few Petabytes extra and enough storage for the lifetime of the system.
On 1st of December 2020 between 07:45 and 16:00 there will be a power outage on Fram compute nodes due to scheduled maintenance on UPS and backup power equipment.
