Changes to this message: Update 3rd Update (Oct 1, 17:15) The cause of the GPFS failure on Saturday, Sep 29 has been identified as a software problem triggered by data migration to additionally installed disk space. Unfortunately, further investigation is still needed before a return to user operation is possible. We will provide an update via this URL once we know more.
