WHAT ARE WE DOING?
Computing will be performing software maintenance work on the Wilson Institutional Cluster (wc.fnal.gov) that will require a downtime.
WHEN WILL THIS OCCUR?
The maintenance begins Wednesday July 6, 7:00 a.m. Central Time. It will end as soon as work is complete, no later than July 8 at 1 p.m.
WHAT IS THE IMPACT TO YOU?
A batch reservation will begin to be put in place 24 hours before the downtime so no batch jobs run during the maintenance period. All user sessions (terminals, backgrounded processes, etc.) will be terminated before maintenance begins. Already queued jobs will resume running after the maintenance period. No logins will be permitted starting early Wednesday morning.
WHAT DO YOU NEED TO DO?
Please be aware of the maintenance work and plan accordingly. Prior to maintenance, please save all of your work, halt running processes and log off both the cluster head and data transfer nodes (wc.fnal.gov, wcio.fnal.gov).
