Cluster Downtime December 19th for Scratch Space Cancelled

Posted by on Wednesday, 12 December, 2012

We have been working very closely with Panasas regarding the necessity of emergency downtime for the cluster to address the difficulties with the high-speed scratch storage. At this time, they have located a significant problem in their code base that, they believe, is responsible for this and other issues. Unfortunately, the full product update will not be ready in time for the December 19th date so we have cancelled this emergency downtime and all jobs running or scheduled will continue as expected.

We will update you with the latest summary information from Panasas when available. Thank you for your continued patience and cooperation with this issue.

Cluster Downtime December 19th for Scratch Space Issues

Posted by on Friday, 7 December, 2012

As many of you have noticed, we have experienced disruptions and undesirable performance with our high-speed scratch space. We are continuing to work diligently with Panasas to discover the root cause and repair for these faults.

As we are working toward a final resolution of the product issues, we will need to schedule an additional cluster-wide downtime on the Panasas to implement a potential resolution. We are scheduling a short downtime (2 hours) for Wednesday, December 19th at 2pm ET. During this window, we expect to install a tested release of software.

We understand this is an inconvenience to all our users but feel this is important enough to the PACE community to warrant this disruption. If this particular date and duration falls at a time that is especially difficult, please contact us and let us know and we will do our best to negotiate a better date or time.

It is our hope this will implement a permanent solution to these near-daily disruptions.
