Cedar System Status

Post date System Status: Update Notes
2019-03-04 - 10:57 PST Online

System fully operational

/project filesystem is mounted on all nodes now.

Finished on March 4, 2019 - 18:56 GMT

2019-02-13 - 16:27 PST Conditions

Scheduled Maintenance March 1-4

Cedar will be unavailable March 1 for required system software updates. Jobs with run times that would extend into March 1 will not be started prior to the outage, and any jobs still running by March 1 will be terminated. 

The system is planned to be back online by the end of the day, March 1, however, data on the /project filesystem will not be available until after March 4 in order to expand the /project filesystem. Therefore, researchers who want to run jobs on Cedar between March 2-4 must copy the necessary files from their /project directories to the /scratch filesystem BEFORE March 1. 

Please, contact if you have questions.

Cedar Fully Operational

 Dec 12,  2018: Cedar is fully operational.

Performance issues on the filesystem were resolved a few days ago. Previous performance issues were caused by specific users. We have adjusted to identify those users more quickly in the future. Sorry for for the inconvenience that may have been caused to your work.

Filesystem Performance Issues

(UPDATED Wednesday Dec. 5th, 1:30pm PST)

The vendor of one of our Lustre filesystem is investigating a possible configuration or tuning problem with the system which would be the cause of the stability issues of the past few days. They have escalated to WhamCloud Tier 3 (the developers of Lustre) to resolve the issue. We do not have an estimated time of arrival for a definitive fix at this time. We apologize for the inconvenience.

Performance issues

There is a problem with some filesystems - this may affect some activity, but not others, but is probably transient. Il y a un problème avec certains systèmes de fichiers. Ceci peut affecter certaines opérations sans en affecter d'autres. Le problème est probablement transitoire.
