POD Cluster Maintenance

June 7, 2016  5:30am – June 8, 2016  6:25am
Carter, Hammer, Peregrine1, Rice, Scholar, Snyder

Carter and Scholar are back online for use as of 6:25am, though they will be operating with many nodes still offline. Staff will be working through Wednesday to steadily increase the number of nodes available. This concludes the POD cluster maintenance.

-----

Carter and Scholar are still being worked on. We will issue another update by 6:00am if not already in service.

-----

The Rice, Hammer, and Peregrine1 clusters have been returned to normal operations as of 1:40am. Work continues on Carter and Scholar, and we will issue an update on those systems by 3:00am if not already in service.

-----

The Snyder cluster has been returned to normal operations as of 12:00am. Work continues on the the other clusters listed here.

-----

The work continues on these clusters, although progress was substantially delayed by the concurrent storage systems failure (Unscheduled Storage Outage). We will post an update by 2:00am or sooner as clusters return to service.

-----

The Carter, Hammer, Peregrine1, Rice, Scholar, and Snyder clusters will be unavailable beginning at Tuesday, June 7th, 2016 at 5:30am, for scheduled maintenance. The clusters will return to full production by Tuesday, June 7th, 2016 at 10:00pm.

During this time, maintenance will be performed on the cooling systems used by these clusters. This maintenance period will also allow critical high-availability fixes to be made to the Research Data Depot while client clusters are offline.

Any PBS jobs which request a walltime which would take them past Tuesday, June 7th, 2016 at 5:30am will not start and will remain in the queue until after the maintenance is completed.
