- Problem with a configuration of site BDII on HG-03-AUTH caused SAM CREAM-CE tests to use incorrect broker and fail reporting WN results on Monday 19th. Workaround was provided to SAM admins and problem was corrected on HG-03-AUTH.
- Problem with sites not publishing WN results correctly (NGI_PL) under investigation. Logs on brokers indicate error on client side.
- broker network upgrade planned next week, see broadcast: https://operations-portal.egi.eu/broadcast/archive/id/817
- incident in the broker network today caused problems to the SAM infrastructure:
POST MORTEM Yesterday a misconfiguration on the EGI message broker instance running at HG-03-AUTH caused publishing of a wrong message broker endpoint information onto top BDIIs. The issue was fixed earlier today at approximately 11:40 EEST. A workaround to the issue was communicated to the administrators to the NGI SAM instances today at 9:43 CET.
This problem caused all the org.sam.CREAMCE-JobSubmit-/ops/Role=lcgadmin tests on NGI/ROC Nagios instances to fail with "proxy expired" error. The impact of the issue is still being assessed.
It will took several hours before CREAM tests come back to function properly as the test jobs already submitted with the information of the bad broker, have to fail for timeout, and only then new test jobs can be submitted.
The incident has an impact on OPS Availability and Reliability statistics of sites. Statistics will be recomputed automatically by the SAM team. There is no need to request recomputations explicitly. A recomputation will be triggered as soon as SAM becomes stable again.
Repository - Network outage last Tuesday and additional unscheduled downtime on 20/11 due to power cut and other infrastructural issues at RAL - assessment of latest list of sites not publishing user DNs and discussion at the OMB. EGI.eu proceeded today with the opening of NGI tickets to foster progress in fixing this problem: https://ggus.eu/ws/ticket_info.php?ticket=88641
