Maintenance on NIRD, NIRD Toolkit, Fram and Saga, 20th April -24th April

Dear NIRD, NIRD Toolkit, Fram and Saga User,

We will have a four day long scheduled maintenance on NIRD, NIRD Toolkit, Fram and Saga starting on the 20th of April, 09:00 AM.

During the maintenance we will:

  • carry out software and firmware updates on all systems

Files stored on NIRD will be unavailable during the time of the maintenance and therefore so will be the services. This will of course affect the NIRD file systems available on Fram and Saga too.

Login services to NIRD, NIRD-toolkit, Fram and Saga will be disabled during the maintenance

Please note that backups taken from the Fram and Saga HPC clusters will also be affected and will be unavailable during this period.

Please accept our apologies for the inconvenience this downtime is causing.

NIRD project file systems mounted on Saga

Dear Saga User,

We have the pleasure to announce that we have now fixed all the technical requirements and mounted NIRD project file systems on Saga login nodes.

You may find your projects in the

/nird/projects/nird

folder.

Please note that to transfer of large amount of files is sluggish and has a big impact on the I/O performance. It is always better to transfer one larger file than many small files.
As an example, transfer of a folder with 70k entries and about 872MB took 18 minutes, while the same files archived into a single 904MB file took 3 seconds.

You can read more about the tar archiving command by reading the manual pages. Type

man tar

in your Saga terminal.

Reorganized NIRD storage

Dear NIRD User,

During the last maintenance we have reorganized the NIRD storage.

Projects have now a so-called primary site which is either Tromsø or Trondheim. Previously we had single primary site, Tromsø. This change had to be introduced to prepare coupling NIRD storage with Saga and the upcoming Betzy HPC clusters.

While we are working on a final, seamless access solution regardless of the primary site for your data, please use the following temporary solution:


To work closest to your data you have to connect to the login nodes located at the primary site of your project:

  • for Tromsø the address is unchanged and is login.nird.sigma2.no
  • for Trondhein the address is login-trd.nird.sigma2.no

To find out the primary site of your project log in on a login node and type:

readlink /projects/NSxxxxK

It will print out a path starting either with /tos-project or /trd-project.
If it starts with “tos” then use login.nird.sigma2.no.
If it starts with “trd” then use login-trd.nird.sigma2.no.

Dear NIRD and NIRD Toolkit User,

During the maintenance we will:

  • carry out software and firmware updates,
  • change geo-locality for some of the projects,
  • replace synchronization mechanisms,
  • depending on part delivery times from disk vendor – expand the storage and quotas.

Files stored on NIRD will be unavailable during the time of the maintenance and therefore so will be the services. This will of course affect the NIRD file systems available on Fram too.

Please note that backups taken from the Fram and Saga HPC clusters will also be affected and will be unavailable during this period.

Please accept out apologies for the inconvenience this downtime is causing.

Missing mounts for Project NS2345K on NIRD

Missing mounts for Project NS2345K on NIRD
The NFS server which is exporting /tos-project1/NS2345K/FRAM to NIRD/FRAM has crashed yesterday around 16:00. We have recovered the NFS server and /tos-project1/NS2345K/FRAM is re-exported agian. We are currently working on mounting the filesystem in login containers and meanwhile investigating the cause. We are sorry for the inconveniences caused.
