Fileservice from cluster.eecs malfunctioning

January 3, 2015 by Lars Rohrbach

After restoring other services following the network upgrade, file service from cluster.eecs and inst-fs.eecs to Soda and Cory clients continues to be severely degraded. This affects anyone who has project shares hosted on cluster.eecs, and servers that mount project shares from cluster.eecs.

Staff have been working with assistance from NetApp support to restore service for cluster.eecs.

We are currently working on various alternatives to make the filesystems accessible again. More updates will be provided on Monday.

cluster.eecs fileservice unresponsive

November 11, 2014 by Lars Rohrbach

We are seeing a high load on cluster.eecs, resulting in NFS fileservice requests being delayed or failing. This affects all project shares hosted on cluster.eecs, and any services dependent on files there. Notably, this includes many research group websites.

Staff are investigating.

UPS Maintenance in SDH 158

August 6, 2014 by Derek Calderon

At 11 AM today we will be replacing batteries and performing maintenance on a faulty UPS located in our primary server and network room for Sutardja Dai Hall. No service interruptions are expected. However, in the event of a failure, there may be a ~5 minute loss of wired and wireless networking in Sutardja Dai Hall, as well as a loss of the NetApp network file storage for the EECS Instructional Labs. The maintenance is expected to last for approximately one hour, but two have been allotted in case of complication.
