TSD Operational Log - Page 6

Published June 29, 2021 8:06 AM

Colossus will have downtime today, 2021-06-29 from 08:00-16:00 to upgrade the Slurm job scheduler software.

We have set a reservation on the cluster so that jobs which request running time during the maintenance windows will not be scheduled from now on. These jobs will remain pending until after the downtime, when they will be rescheduled automatically. The submit hosts will be accessible, but cannot be used to submit jobs to Colossus.

During the downtime we advice you to keep an eye on this operational log for any updates.

The group management pages in selfservice hasn't worked properly after the maintenance earlier this week.

There can be cases where a users haven't been added to groups.

Published June 17, 2021 9:40 AM

Users experience random job submission failures with an error message similar to:

"sbatch: error: Batch job submission failed: Socket timed out on send/recv operation."

We're actively working on a solution.

Selfservice is down for planned maintenance June 15.

Update June 15, 18:28: To ensure that all functions are working as normal, we will keep Selfservice in maintenance mode until tomorrow.

Update June 16, 10:42: We will reenable selfservice around 12.00 today.

Update June 17, 11:15: Most parts of selfservice should work as normal. Please contact tsd-drift@usit.uio.no if you experience any problems.

Currently, we are experiencing problems with managing groups of a TSD-project via TSD Selfervice, while logging in with ID-Porten (MinID, BankID, Buypass, Commfides). As a temporary workaround, please log in via TSD Credentials, to perform this task of managing groups in your TSD-project.

 

Update May 20: The problems have been resolved

Som informert tidligere i ?r (ca. slutten av januar) skulle vi fra 1. mai ha innf?rt lisenskostnader for Windows i TSD. TSD rapporterer n? bruk av Microsoft-produkter i TSD til Microsoft p? m?nedsbasis, basert p? antall personer med faktisk tilgang. Grunnet noen sm? tekniske utfordringer har vi n? valgt ? utsette avregningen til 1. juni.

Innen 1. juni vil Prosjektleder i TSD, via selvbetjeningsportal, kunne styre  hvem som skal ha tilgang til de ulike tjenestene ved ? melde folk inn og ut av grupper. Vi vil publisere fremgangsm?ten for ? styre inn-, og utmelding av prosjektets medlemmer p? denne lenken:

The cost command, used to query cpu quota usage on Colossus, is currently not working for projects without Sigma2 quota. 

Update: the cost command now displays usage stats for Sigma2 quota, and will display NA and an info message for projects without Sigma2 quota.

Published Mar. 26, 2021 10:51 AM

Starting from April 1st., we will be introducing the following changes in the distribution of Colossus Quotas:

  • We will reduce the Sigma2 pool of resources to 1536 cpu cores, with no gpu nodes. Only TSD-projects with cpu hour quota from Sigma2 can use this pool.
  • We will move the removed resources from the Sigma2 pool to a dedicated resource, called “tsd”, consisting of 288 cpu cores on ordinary compute nodes, plus 128 cpu cores and 4 gpu cards on two gpu nodes.
  • All TSD-projects can use the “tsd” resource, by submitting jobs using "--account=pNN_tsd" instead of "--account=pNN". Please check this document, for the complete procedure:
    /english/services/it/research/sensitive-data/use-tsd/hpc/dedicated-resources.html
  • There will be a limit of 200,000 cpu hours on “tsd” resource, as it is limited. However, we may increase this limit in future.

Its also affecting /cluster on the Colossus compute nodes. The majority of compute nodes have been rebooted which may have affected running jobs.

Update 12:00: The submit hosts and Colossus are currently unavailable.

Update 14:00: The issue has been resolved, and we're rebooting the submit hosts now.

Due to an outage, login through VMware is currently unavailable.
You should however still be able to login through https://login.tl.tsd.usit.no if your project has a Linux-VM.

We are working on getting things back to normal as quickly as possible.

The storage system for project storage (not Colossus) is having performance issues. This is causing instability in file import and export, and some slowness on virtual machines. We are debugging and fixing this.

Consent Portal from registration temporary due to service modification. This does not mean that consent is no longer acquired. The consents will be delivered to your project normally. The already registered forms will continue to be exposed to consenters on the external portal. We expect to resume form registration in couple of days.
