Sep. 28, 2012: Bugaboo Shutdown

Because of a power outage in the datacentre the Bugaboo system needs to be powered off on Friday, Sep. 28, 16:00 (Pacific).

All jobs that are still running at the time of the shutdown will get terminated. The system will not start jobs with a walltime that would extend into the shutdown period.

We expect that the system will become available again late Friday evening.

Fixed: Hungabee Unscheduled Outage - 21 Sept 2012

25 Sept - 1600h:  Hungabee is now back in production.

25 Sept - 1000h:  During final testing, the UV100 login node was restarted.

24 Sept - 1800h:  Further analysis showed that the problem was software-related. A workaround has been arranged and final testing is scheduled to be completed overnight. If this testing is successful, the UV1000 will be put back in production tomorrow morning.

24 Sept - 1400h:  New information has become available indicating the problem may be hardware-related.  It is now unlikely the UV1000 will be back in production today.

24 Sept - 1300h:  Testing continues.  Unless new information indicates otherwise, the UV1000 will likely put back into production later today.

21 Sept - 1630h:  The UV1000 was once again restarted but, due to the ongoing instability, it will be left out of production over the weekend for testing purposes.

21 Sept - 1400h:  The UV1000  (2048 core compute node) crashed again. 

21 Sept - 1300h:  Hungabee has been returned to full production.

21 Sept - 1230h:  The UV1000 was successfully restarted.  The hardware vendor was engaged to help search for the cause of the failure, but none was found.  Some diagnostic mechanisms failed to work as expected during the failure, and we are working with the vendor to determine the cause of this, so that future failures can be properly diagnosed.

21 Sept - 1030h:  Access to the login node of Hungabee has been restored.  The UV1000 compute node remains down.  We are continuing to investigate.

21 Sept - 1000h:  Hungabee is not currently available.  The cause of this outage is not yet known.  We are investigating and will report more detail as it becomes available.
