Owens
Rolling reboots on owens and pitzer starting 26 July 2021
We will have rolling reboots of Owens and Pitzer cluster, including login and compute nodes, starting from 9am on July 26, 2021. The rolling reboot is for urgent security updates. The rolling reboots won't affect any running jobs, but users may experience longer queue wait time than usual on the cluster. User will also expect about a 10 minute outage of login nodes during the reboot of login nodes. If there are interactive jobs started from a login node and that login node is rebooted, then the job will be killed.
Please review your usage of /fs/ess
Recent improvements to a routine OSC accounting process resulted in larger adjustments to file counts and quota usages than anticipated for some accounts. The updated metrics are more accurate but some users may now have less free space than expected. Please review your usage closely and, if necessary, remove unneeded data or request a quota expansion via OSCHelp to avoid exhausting your available space.
Submit FY22 budget on July 1, 2021
Due to an error in the OSC Client Portal (my.osc.edu), PIs will not be able to submit an FY22 budget on June 30, 2021. Please create a new current budget on or after July 1st, 2021 to reactivate your project. We apologize for the inconvenience.

System Downtime June 30, 2021
A downtime for all OSC HPC systems is scheduled from 7 a.m. to 9 p.m., Wednesday, June 30, 2021. The downtime will affect the Pitzer and Owens Clusters, web portals, state-wide licenses, and HPC file servers. Login services will not be available during this time. Client portal (my.osc.edu) will be accessible.
In preparation for the downtime, jobs that cannot be completed before 7 a.m., June 30, 2021 will not start. Jobs that are not started on clusters will remain until after the downtime and then will be queued to start once the system is returned to production status.
Problems with GPFS filesystem
We are experiencing some problems with GPFS filesystems this morning (Thursday, June 10). OnDemand is not working. It may also cause unexpected job failures. We are working hard to fix this issue, and will provide more updates once we know more.
