Fram MDS patched

Dear Fram User,

This morning around 09:05, once again has the Fram metadata server crashed and likely had impact on running jobs.

A mitigating patch was delivered by the vendor yesterday and we used this opportunity to apply it on our metadata servers.

We will keep the system closely monitored and cooperate with the vendor on further stabilizing the system.

Apologies for any inconvenience this may have caused!

Clean-up of Fram filesystem needed

Dear Fram users,

The Fram filesystem, and most critically /cluster/work and /cluster/home, is running out of inodes, and there is only 8% left. If we run out of inodes it will not be possible to create new files. To avoid loss of data and job crashes we kindly ask all of you to if possible delete files that you no longer need.

Best regards,

Jon, on behalf of the Operations Team

  • 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.
