Today's downtime rescheduled to Monday, February 25

[chtc-users@xxxxxxxxxxx]

Hi CHTC users,

This message is for users of our high throughput compute (HTC system).

Due to the last-minute discovery that today's planned downtime would affect more HTC services than anticipated, we are pushing it back a week to next Monday, February 25.Â

The following resources will be unavailable or taken down during the downtime:

• submit-1 and most research group-owned submit servers
  
• the high memory servers
• the Gluster file share and transfer server
  
• about half of our execute servers
  

Implications for HTC jobs:

• Any jobs running on the affected execute servers (including the high-memory servers) will be evicted when the maintenance window begins on Monday, February 25. Evicted jobs will remain in the queue and be re-run automatically.
  
• Jobs submitted from submit-1 or a research group-owned submit server may be interrupted if they are running when the maintenance window begins on Monday, February 25. These jobs will also remain in the queue and be re-run automatically.
  
• Gluster-dependent jobs that haven't started by the morning of Feb 22 will not run until after the downtime completes on Feb 25.

Get in touch with us at chtc@xxxxxxxxxxx with any questions and concerns.

Cheers,

Your CHTC team
