Monitoring - A software bug is causing frequent restarts of the underlying infrastructure behind Freezer. An upgrade to resolve this is planned for Monday morning.

Investigating - Freezer was down briefly from Friday 2025/11/28 12:40PM until Friday 2025/11/28 12:46PM. Please check if your transfers have been interrupted. For more information see https://docs.nesi.org.nz/Storage/Long_Term_Storage/Freezer_Guide/#synchronise-data

Update - There has been a period of IO stalls this morning as we've dealt with some storage hardware failures. That issue is now resolved, however space reclamation continues in the backend and is having a detrimental impact on read performance. We are working with WEKA support to look at mitigation options. Apologies for the performance impact - if your jobs are impacted and need a runtime limit extension then please reach out to support.

Identified - Our storage system is currently very full and this is forcing the backend object storage to undertake some urgent administration by way of defragmentation. This increased load is having a detrimental affect on I/O performance, especially read I/O, and this is likely to continue for some days. We are urgently looking at ways to mitigate this. Researchers could help alleviate this in the short term by cleaning up any unwanted files and data as soon as possible please.

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.

Automatic cleaning launched for scratch filesystem (/nesi/nobackup) - Announcement Nov 20, 2025 09:00 - Nov 21, 2025 09:00 NZDT
As announced earlier, we’ve re-activated an automatic cleaning process for temporary data stored on our scratch filesystem (/nesi/nobackup). Project members with files scheduled for deletion were notified by email (Subject to their my.nesi.org.nz Notification preferences. To confirm or adjust what notifications you receive, follow these instructions: https://docs.nesi.org.nz/Getting_Started/my-nesi-org-nz/Managing_notification_preferences/)
Files will be deleted on Wednesday 03 December (two weeks from yesterday's email notification). For more details on how the auto-deletion process works, visit:
https://docs.nesi.org.nz/Storage/File_Systems_and_Quotas/Automatic_cleaning_of_nobackup_file_system/
If you have files identified as candidates for deletion that you need to keep beyond the scheduled expiry date, you can move them to your project directory or to Freezer, our long-term storage service. However, if you plan to move more than 2 TB of data or if you need to increase your project directory quota, email support@nesi.org.nz so that we can discuss your storage needs and assist you.
