Upcoming Maintenance Period Extension Required January 31-February 7 (estimated)

Filed under: Uncategorized — Jeff Valdez @ 11:51 am

WHAT IS HAPPENING? 
PACE is updating the group ID of every group & file in our storage infrastructure to remove the conflicts with those assigned campus wide by OIT. The expected time per cluster varies greatly due to the size of the related storage. During the maintenance period, PACE will release clusters as soon as each is complete.  

WHEN IS IT HAPPENING? 
Maintenance period starts on Tuesday, January 31, 2023. The changes to the Phoenix project file system are estimated to take seven days to complete. Thus, the maintenance period will be extended from the typical three days to seven days for the Phoenix cluster. The other PACE clusters (Hive, Firebird, CoC-ICE, PACE-ICE, and Buzzard) are anticipated to finish earlier. PACE will release them as soon as maintenance and migration work are complete. Researchers can expect those clusters to be ready earlier.   

WHY IS IT HAPPENING? 
This is a critical step for us to be able to make new storage available to campus users, removing group-id conflicts we currently have with the Georgia Tech Enterprise Directory (GTED). This will allow us to provide campus and pace mountable storage to our researchers and provide a foundation for additional self-service capabilities. This change will also allow us to evolve the PACE user management tools and processes. We understand that the short-term impact of this outage is problematic, but as we increase storage utilization, the problem will only get worse if left unaddressed. We expect the long-term impact of this update to be low, since the ownership, group names and permissions will remain unchanged. 

WHO IS AFFECTED? 
All users across all PACE’s clusters.  

WHAT DO YOU NEED TO DO? 
Please plan accordingly for an extended Maintenance Period for the Phoenix cluster starting Tuesday, January 31, 2023. The other PACE clusters (Hive, Firebird, CoC-ICE, PACE-ICE, and Buzzard) will be released as storage updates are completed during the maintenance window. If you have a critical deadline that this will impact, please let us know and we can collaborate on possible alternatives.  

WHO SHOULD YOU CONTACT FOR QUESTIONS? 
Please contact PACE at pace-support@oit.gatech.edu with questions or concerns. If escalation is required, please email me, Pam Buffington pam@gatech.edu directly as well.

Best, 
– The PACE Team
