JHPCE Cluster Maintenance – Thursday, August 27th from 6:00 PM – 10:00 PM

On Thursday, August 27th from 6:00 PM – 10:00 PM, we will be performing Maintenance on the Amber1 storage array to upgrade its Operating System.   We have had a number of issues with the Amber1 array in the recent past, and the root cause appears to be a memory leak in the current version of the OS, thus the vendor is recommending the upgrade.

This storage array is used for home directories on the JHPCE cluster, so logins to the cluster will be disabled during this time.  We are recommending that jobs not be run on the cluster during this maintenance window.  From our experience, when we have performed work like this in the past, jobs have generally paused while the array was unavailable and then resumed once the array is back, but we are still strongly recommending that you avoid running jobs during this maintenance window.  We apologize for any inconvenience.
