  • 2018-05-02:  Sandhills: Unscheduled maintenance required
    Category:  Maintenance

    Sandhills requires maintenance on one of the servers that provide the /work file system.

    Running jobs will be suspended and pending jobs will remain queued during the maintenance.

    Any access to files under /work will block on the login or the Globus transfer nodes during the maintenance.

    A follow-up announcement will be sent when the maintenance is completed.


  • 2018-04-20:  Anvil: Filesystem issues
    Category:  Maintenance

    Earlier today the filesystem backing Anvil experienced some issues which may have caused instances to hang. We suggest users check running instances and perform a hard-reset if they suspect slow or strange performance.

  • 2018-03-16:  Crane /work filesystem downtime resolved
    Category:  General Announcement

    The /work filesystem for Crane is restored as of 2:50pm.

    One of the storage servers crashed and rebooted. A filesystem check was completed with no errors found. Running jobs which were accessing /work stalled until the filesystem was restored. This may have caused jobs to exceed their time limit. There was no data loss from this outage.

    We believe the storage server crash was triggered by I/O delays as the RAID controller was rebuilding a failed disk drive. The rebuild is still running and we are monitoring the system.
