Scheduled Maintenance

WEKA filesystem and compute core changes - Announcement Sep 8, 2025 09:00-17:00 NZST

In order to get our new WEKA filesystems up to their best possible performance we need to dedicate some cores on each compute node for exclusive use by WEKA. So on Milan nodes Slurm jobs will only be able to use 126 cores per node rather than 128, and on Genoa nodes 166 rather than 168.
This change has already begun, having already been applied to all of the Milan nodes and the majority of the Genoa nodes. We expect to be doing the last of the Genoa nodes on September 8th.

Cumulus switch upgrades Dec 2, 2025 18:00 - Dec 3, 2025 06:00 NZDT

Update - This maintenance has now been postponed to Dec 2nd at 1800hrs
Nov 18, 2025 - 08:50 NZDT
Scheduled - The border switches will have an upgrade applied overnight on Nov 18th from 6pm. Any ssh and external connections to the cluster and OnDemand may get broken during this maintenance. Slurm jobs will be unaffected.

OnDemand user/group resolution issue causing file access errors
Resolved - This incident has been resolved.
Nov 18, 10:48 NZDT
Monitoring - We have done a rolling restart of NFS services which look to have resolved the user/group resolution issues in OnDemand and the correct mappings are now being displayed

We are now monitoring for any further impact.

If you notice any other problems with OnDemand then please let us know.
Nov 17, 17:06 NZDT
Identified - We've identified the underlying cause of the issue and revised down our understanding of the impact. OnDemand apps such as Jupyter are working and able to access user's files consistently with user and group permissions on the main cluster, despite displaying as nobody:nobody. The "NeSI HPC Shell Access" feature is still impacted due to additional ownership checks in SSH, users that need help connecting via SSH can reach out to support.

We are now planning a rolling restart of NFS services later this afternoon which should resolve the user/group resolution issues in OnDemand and result in the correct mappings being displayed.

If you notice any other problems with OnDemand then please let us know.
Nov 17, 13:14 NZDT
Investigating - We have encountered an issue with user and group resolution that is currently impacting OnDemand sessions. Users may be experiencing file listing permissions showing as "nobody:nobody" and getting permission denied when trying to read files. This is also impacting the "NeSI HPC Shell Access" feature in OnDemand. Regular/native SSH access to the cluster is not impacted.

Apologies for the Monday disruption, we're investigating workarounds and will provide an update at approx 1pm.

Current running sessions will be affected during this time as we will be doing some behind the scene updates.

We advise that all work is saved prior to this change, after the update all previous running sessions will not be active and new sessions will need to be created.

We apologize for any inconvenience caused at this time
