System Downtime

Date: 
Tuesday, July 12, 2016 - 7:00am to 9:00pm
Location: 

Ohio Supercomputer Center

7/12/16 7PM Update: Downtime is now estimated to complete around 9:00PM, not 5PM.

UPDATE: Due to a bug identified on some of the center's new hardware, our planned June 29th downtime to upgrade project and scratch file systems will be postponed until July 12th. This delay is not expected to alter the availability timeline for our new cluster, Owens.

 

The rescheduled downtime for all HPC systems is Tuesday, July 12, 2016, beginning at 7 a.m and expected to finish by 5 p.m. The downtime will affect the Oakley and Ruby clusters, web portals, and HPC file servers. Login services and access to storage will not be available during this time.
 
In order to quiesce the system for an orderly shutdown the batch scheduler will begin holding jobs that cannot complete before 7 a.m. July 12th.  Jobs that are not started will be held until after the downtime and then started once the system is returned to production status.
 
Highlights of the downtime activities:

  • Migration of data to new Project and Scratch file systems 
  • Hardware preparation for Owens cluster
