Tuesday June 10, 2014 starting at 6am -- Pause of Cluster Batch Schedulers for Network routing changes

Posted: June 6, 2014

Duration: several hours

In working to resolve a number of file system and network slowness issues that have been observed over the past several weeks due to a combination of a number of reasons, CHPC will be making changes to the network routing between the clusters and the file systems. We expect the work to take a couple of hours.

In order to make the changes, the schedulers on the clusters will be paused at 6am. This means no jobs on these clusters will start and that jobs will not exit the batch system when done during this window.

If we identify any additional impacts to users I will send another notice on Monday.

When the new routing is in place, CHPC staff will work to clean up any residual issues in the batch queue and also to make sure that desktop mounts of the file systems are available.
