Reported Outages

A maintenance session of CHI@TACC is scheduled from September 1st, 3 AM Central Time to September 2nd, 6 PM Central Time. All bare-metal resources at TACC have been reserved for this purpose. KVM@TACC and CHI@UC will remain available.

Update: CHI@UC is once again available following the outage.

--

CHI@UC will be unavailable until tomorrow morning. Power to the building housing the resources will not be turned on until 6am. Once we have power, we'll begin the process of bringing up the cluster. We're hoping to resolve this outage by mid morning. Thank you for your patience.

Update: Connection to the authentication server has been reestablished, CHI@UC is now operational.

CHI@UC is temporarily unavailable due to a problem with our authentication server located at Chicago. We currently do not have an ETA on when the server will be available again.

Update: The issue has been resolved.

KVM@TACC is experiencing some issues with its networking infrastructure. Access to instances may not be possible. We expect to restore availability later today.

Update: CHI@UC has been restored. Thank you for your patience. If you experience any issue please open a ticket via our helpdesk.

We have received notice from the building housing the CHI resources at the University of Chicago that they will be performing power work starting on Friday, June 17th 2016.

REMINDER:

Dear Chameleon users,

We have received short notice from the building that they will be performing power work in the datacenter housing the CHI resources at the University of Chicago on Monday, May 9th 2016.

CHI@UC will be unavailable starting at 08:00 AM CST. Work is expected to last approximately 12 hours plus recovery time on our end. An all clear message will be sent out once the work has been completed.

NOTE: Instances may not be available after the maintenance period. We recommend that you snapshot your work ahead of time.

Update: The work has been completed.

In order to apply routine software updates, the Chameleon virtualization cluster at TACC (KVM@TACC) will be unavailable on Tuesday March 1, 2016 from 7:00 to 9:00 AM Central Time. During the work all API endpoints, the dashboard, and networking will be unavailable. Instances are not expected to be interrupted, but will not be accessible.

We discovered a configuration problem related to the upgrade of CHI@TACC which meant that since service was resumed on Friday, your instances could have been scheduled on different nodes than the ones you reserved. If during the week-end you gathered experiment results that require specific hardware, you should unfortunately discard them.

While we fixed this issue, we had have to terminate all active reservations and instances.

Update: CHI@UC is now available as we have finished migrating services to a new server.

CHI@UC was scheduled to be unavailable for a short period of time from 08:00 AM on Thursday, February 18, 2016 in order to apply security updates and perform a small hardware maintenance. Due to hardware issues we needed to extend the maintenance.

CHI@TACC has been upgraded to OpenStack Liberty, and has been restored to service.

Users who use automation should note that the network ID used when booting nodes has changed, and how has the UUID 915853fe-10c5-4dac-a402-ef1ebc53e427.
