  • CONTINUED DELAY: Grace Cluster and GPFS Filesytem

    Friday, May 8, 2015 - 9:30am

    The Grace Cluster and GPFS Filesystem coming back online has been delayed.  The cluster has been experiencing network problems and so far the issue has been narrowed to the storage network.   There is no impact to the underlying filesystem or storage of data.

    The team will continue to addess the issue over the weekend and will continue to post updates to the website as more information is available.  At this time we are not expecting resolution before Monday.
