[COMPLETED – 6:51 PM 2/28/2020]

We are pleased to announce that our February 2020 maintenance period (https://blog.pace.gatech.edu/?p=6676) has completed ahead of schedule. We have restored access to computational resources, and previously queued jobs will start as resources allow. The login nodes and storage systems are now accessible. 

As usual, there are a small number of straggling nodes that will require additional intervention.  

A summary of the changes and actions accomplished during this maintenance period are as follows: 

  • (Completed) RHEL7 clusters received critical patches
  • (Completed) Updates will be made to PACE databases and configurations.
  • (Deferred) [Hive, Testflight-CODA clusters] Power down all of the research hall for Georgia Power reconnections
  • (Completed) [Hive cluster] Replace failed InfiniBand leaf on EDR switch
  • (Completed) [Hive cluster] InfiniBand subnet managers will be reconfigured for better redundancy.
  • (In Progress) [Hive and Testflight-CODA clusters] Lmod, the environment module system, will be updated to a newer version.
  • (Completed) [Hive cluster] Run OSU Benchmark test on idle resources
  • (Completed) [GPFS file system] Apply latest maintenance releases and firmware updates
  • (In Progress) [Lustre file system] Apply latest maintenance releases and firmware updates

Thank you for your patience!

[UPDATE – 8:52 AM 2/27/2020]

The PACE maintenance period is underway. For the duration of maintenance, users will be unable to access PACE resources. Once the maintenance activities are complete, we will notify users of the availability of the cluster.

Also, we have been told by Georgia Power that they expect their work may take up to 72 hours to complete; as such, the maintenance outage for the CODA research hall (Hive and Testflight-CODA clusters) will extend until 6:00 AM Monday morning. We will provide updates as they are available.

[Original Message]

We are preparing for PACE’s next maintenance days on February 27-29, 2020. This maintenance period is planned for three days starting on Thursday, February 27, and ending Saturday, February 29. However, Georgia Power will begin work to establish a Micro Grid power generation facility beginning on Thursday, and while work should complete within 48 hours, any delays may extend the maintenance outage for the Hive and Testflight-CODA clusters through Sunday instead; PACE clusters in Rich will not be impacted by any delays in Georgia Power’s work. Should any issues and resultant delays occur, users will be notified accordingly. As usual, jobs with long walltimes will be held by the scheduler to ensure that no active jobs will be running when systems are powered off. These jobs will be released as soon as the maintenance activities are complete. We are still finalizing planned activities for the maintenance period. Here is a current list:

ITEM REQUIRING USER ACTION:

  • None

ITEMS NOT REQUIRING USER ACTION:

  • RHEL7 clusters will receive critical patches.
  • Updates will be made to PACE databases and configurations.
  • [Hive, Testflight-CODA clusters] Power down all of the research hall for Georgia Power reconnections
  • [Hive cluster] Replace failed InfiniBand leaf on EDR switch
  • [Hive cluster] InfiniBand subnet managers will be reconfigured for better redundancy
  • [Hive and Testflight-CODA clusters] Lmod, the environment module system, will be updated to a newer version
  • [Hive cluster] Run OSU Benchmark test on idle resources
  • [GPFS and Lustre file systems] Apply latest maintenance releases and firmware updates
