    The Firefly Panasas storage is suffering performance issues. We will need to take Firefly offline for up to 24 hours in order to run complete systems check and upgrade the filesystem driver on all the worker nodes.

    During this time, logins will be disabled and all jobs will be terminated on Firefly.

    An announcement will be sent out once Firefly is back online.

  • 2011-01-11:  Firefly /work space unavailable.
    Category:  General Announcement

    Firefly's /work space is temporarily unavailable. Our storage system lost a storage blade and the system preemptively took the /work volume offline to prevent further issues.

    Your running jobs accessing /work will stall until /work is back online. You do not have to terminate your jobs.

    We are working on restoring service.

    PRAIRIEFIRE: Service restored


    PRAIRIEFIRE maintenance is complete. If you were running jobs on the cluster prior to the shutdown, please login and restart them. PRAIRIEFIRE is now using different (improved) network file servers - if you experience problems with I/O on the system please let us know.
