As of 9:00am, are seeing a problem with the LustreC scratch filesystem that serves Carter, Hansen, and Peregrine1. To prevent any more jobs from running into this, we have temporarily suspended scheduling of new jobs, though you may still submit to queues.
Our engineers are working to resolve this as soon as possible.
10:00am UPDATE: The problem was triggered to a temporary glitch in the networking and it has been fixed now. All systems have been return to normal operation. We are sorry for any inconvenience this may have caused.
