Unplanned /scratch Outage

At 7:29 PM on April 18, 2012 a hardware failure occurred on the metadata server of the /scratch Lustre filesystem. This failure caused loss of the ability to list and create new files on /scratch. The issue was mitigated at 8:15 PM on April 18, 2012 and access has been restored. Root cause of this issue is being investigated. We apologize for the inconvenience.
