Cluster Maintenance - Carter
Carter has been return to normal operations. All queues have been enabled.
Update: December 2, 2015 12:15pm
Carter is mostly ready to return to service, but the site-wide home filesystem has suffered a failure which is preventing this from being completed (Unscheduled Home Filesystem Outage). We will update this as soon as that failure is resolved.

The major work on the scratch filesystem has concluded, and we are in the process of returning the cluster to full service. We expect Carter to be back in normal operations by noon or earlier, and will update this post as soon as it is.
