Pawsey Supercomputing Research Centre Status

Investigating: Currently, Data Portal and pshell users may be experiencing unusually long wait times downloading files from banksia. This will sometimes end in errors (eg timeout or content not available) however the banksia scheduler will still eventually bring the files back online and you will be able to download when trying again a day or so after the initial attempt. We are currently investigating this with the vendor as a potential scheduler issue.

Investigating: We have resolved most of the instability between Mediaflux and the tape storage system. Some minor issues remain which we are continuing to monitor and work on.

Investigating: Work continues with two Vendors to get this resolved. We will be making and testing some recommended steps today to see if this can be completely resolved.

Investigating: A setting was adjusted on the Mediaflux server and this has improved success rate for obtaining files however some issues still remain which we are still investigating with the vendor.

Investigating: We are aware of an issue that may be affecting some users attempting file transfers with Mediaflux (data portal and pshell.) It is currently being investigated.

Resolved: All OSTs in scratch are operational and we will continue to monitor the filesystem over the weekend.

The issue may have been caused by the flash pool becoming critically full.

Please remember that the scratch filesystem is a shared resource for the temporary storage of results of simulations and data processing.

Please be mindful of other researchers, and do not store unnecessary data.

Monitoring: The problematic OSTs have been checked and /scratch is fully operational.

Investigating: HPE have reported two of the OSTs have "journal errors" are are performing a check.

Investigating: Two OSSes have failed.

Investigating: There is performance degradation in relation to the "/scratch" filesystem

• This is related to SSD storage OST pools being close to full capacity
