Spring Down Maintenance: Tuesday, 30-Mar-2021

On Tuesday, 30-Mar-2021, we will be performing minor maintenance on the central CLASSE infrastructure cluster, the CHESS-DAQ cluster, and networking for the Compute Farm and Wilson Lab East Module. No outages are anticipated, although there is the potential for glitches to occur (up to a few minutes long). Please submit a ServiceRequest with any questions or concerns about this maintenance work.

[Correction 25-Mar-2021: There will be a one-hour network outage in the Wilson Lab East and Center Modules on Tuesday, 30-Mar-2021, 1:00-2:00 PM.]

End of the CHESS 2021-1 Run

Tuesday, 23-Mar-2021, marks the end of the 2021-1 CHESS run, during which 130 TB of raw data was collected on the CHESS-DAQ filesystems. Per the usual CHESS data management procedures, the raw data will become read-only on Thursday, 25-Mar-2021 at 10:30 AM in preparation for the final archive to tape. We will schedule the final rotation when the archive completes, at which point the raw data from 2020-3 will be removed from disk and the CHESS-DAQ will be set up for 2021-2.

General network and server maintenance will occur every Tuesday from 12:00 noon to 2:00 PM. The CLASSE-IT group will always announce any expected disruptions in our NewsLetter and via CLASSE-IT-NEWS-L, but with the size and complexity of our network there is always the potential for something to go wrong. We will do our best to contain all network maintenance and planned outages to Tuesdays from 12:00 noon to 2:00 PM.

Unless other arrangements have been made, CLASSE-managed Windows systems may be updated and rebooted on Tuesday morning at 2:00 AM, so please avoid critical or lengthy operations at that time. For more details, please see SystemExpectations.
