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.

Scheduled downtime – NIRD storage expansion – 2nd of April

Update:

  • 2019-04-03 13:25: NIRD and the service platform are back into production.
  • 2019-04-03 10:59: Maintenance work has finished. We are proceeding in starting back the filesystems and services.
  • 2019-04-03 08:22: Disk expansion and rebalancing is finished. HW checks are currently ongoing and shall finish in a couple of hours. Will keep you posted.
  • 2019-04-02 09:55: NIRD filesystems are unmounted from Fram and replicated data is available read-only trough login-trd.nird.sigma2.no
  • 2019-04-02 08:06: Maintenance work has started.

Dear NIRD User,

NIRD and the Service Platform will be under maintenance to expand the disk capacity in Tromsø.

The operations for storage expansion and disk pool rebalancing will start on the 2nd of April at 8:00 am CET and will last for maximum 2 days. During the maintenance, the services running on the NIRD Service Platform and on the NIRD Toolkit will not be available.

During the downtime we plan to make project data mirrored to Trondheim available in read-only mode trough a specially built login node. This solution will be first tested with real load during this downtime, thus we might encounter some technical difficulties.
That being said, to access the remote, mirrored data, please login to login-trd.nird.sigma2.no.

We apologise for the inconvenience.

Short outage on Service Platform

Servers running the Service Platform and NIRD login nodes, have some issues with the remote filesystems.
The problem is already identified and being taken care of, but you might experience short hiccups until the problem is fixed on all the affected nodes.
You will have to re-login to NIRD login nodes.

We expect to be ready in maximum one hour.

Fram is in service again

Dear Fram users,

after more than 16 days of downtime, losing more than 12 million CPU hours, we were finally ready to return the system to service tonight.


This downtime has been a very unpleasant experience to us, and we sincerely understand that this has been annoying and causing distress to our users depending on the service.

The main reason for the downtime has been severe problems with the global file system on Fram, forcing us to halt the system and escalate towards the file system vendor until their engineers were able to analyse and repair the different issues experienced.

Sincerely, Jørn Amundsen, UNINETT Sigma2 AS
