Monitoring
We have identified a number of problematic jobs that were causing problems for the storage system and stopped them. The system appears to be stable but we are closely monitoring it for signs of additional problems.
Research NAS users may now establish new jobs.

Identified
OIT is still working to resolve continuing NAS performance issues (slowness in client connections over NFS) on research storage impacting the following NAS servers:
Research Toolkits (Rapid VMs) and Research Computing (DCC) home and group directories are also impacted by this issue.
We have disabled logins to the Duke Computer Cluster while we continue to work on this issue.
At 10 pm we will disconnect client connections to the research NAS. At that time all client connections from Research Computing services will be interrupted for up to 10 minutes. Most clients will automatically reconnect after the reset.
We ask that research NAS users do not establish new jobs on any services until we conclude these activities.
