[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.
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.
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.
Dear NIRD and NIRD Toolkit user: NIRD-TOS is currently down and will remain unavailable until Wednesday 12:00. We are replacing all cables during the next coupe of days.
Note that NIRD-home is also not available during that time.
All remote mounts on Fram, Saga and Betzy using NIRD-TOS will be unavailable until downtime is over
We will have downtime the following week to try again to replace all internal cables in NIRD-TOS and Fram storage systems.
NIRD-TOS (Including the toolkit) will be down from 08:00 Monday 2nd November to wednesday 4th 12:00
Fram will be down from Wednesday 4th 08:00 until Friday 6th 12:00
There is still a chance that the downtime will not happen, but proper notification will be given in the opslog. Unfortunately the current situation with Covid-19 makes it difficult to make detailed plans.
We apologize for any inconvenience.
The downtime for NIRD-TOS on 26th October until 29th October is cancelled and the downtime for Fram from 28th October until 29th of October is cancelled.
New dates for the downtime will be announced monday 26th or tuesday 27th.
During the downtime we will replace all internal cables between disk controllers and disk enclosures. The firmware upgrade two weeks ago helped a lot, but we are still seeing ccommunication errors so the decision is to remove all cables and replace them.
All services and file systems are now back in operation, including NIRD-Services and NIRD mounts on HPC systems
Please be aware that some projects on NIRD has changed home systems from NIRD-TOS to NIRD-TRD and vice versa.
Vilje filesystem has been fixed with good help from DDN and we are now open for business.
Please be aware that some files may have been lost.
Always back up your files.
