2. Operational issues

2.1 Report from DMSU

ARGUS/WMS Certificate Chain Mixups

• Affecting several sites, where WMS is unable to make SSL connection to ARGUS.
• With all probability this is a combination of using curl from the SL6 distribution, which in built with NSS SSL rather than OpenSSL and, as such, does not really support proxy certificates, and a bug in Java, hopefully fixed since Java 7 Update 60.
• Related issues:
  • https://ggus.eu/index.php?mode=ticket_info&ticket_id=101486
• This issue is already being investigated at 3rd level but PTs cannot decide who is responsible ant DMSU is overseeing.

CREAM CLI/GridSite SegFaults at Long-Lived Proxies

• glite-ce-job-submit crashes if the user's proxy certificate has a lifetime exceeding 240 hours (10 days)
• 2 issues:
  • one in GridSite for the segfault, forwarded to the GridSite PT to fix - UPDATE - fix provided wih GridSite v. 2.2.5 (issues #15)
  • one in caNL-c - UPDATE - fix provided with caNL-c v. 2.1.5, issue #6
• Related issue:
  • https://ggus.eu/?mode=ticket_info&ticket_id=104009
  • https://ggus.eu/?mode=ticket_info&ticket_id=105893

L&B & CREAM Update Issues - on EMI repositories

• UPDATE
  • EMI 3 Update 18 solves some of the issues introduced with the previous update:
    • L&B v. 4.1.2

2.2 Migration of Central SAM services & reconfiguration of NGIs SAM instances

Action closed:

• Central SAM services were migrated from CERN to the new consortium (GRNET, CNRS and SRCE). In order to enable smooth transition we have agreed to start using new hostnames:
  • mon.egi.eu for grid-monitoring.cern.ch
  • opsmon.egi.eu for ops-monitor.cern.ch

• All Regional & VO SAM instances were reconfigured.

2.3 EMI-2 decommissioning

• Probes are running in midmon: Documentation.
  • All products but dCache are being retired as previously announced. dCache extended the support for the 2.2.x versions until July 2014.
  • Important Notes:
    • APEL is one of the UMD 2/EMI 2 services no more supported - but there are still sites (23 sites as of 15.06.2014) publishing accounting information using UMD 2/EMI 2 APEL clients - see list available at: APEL consumer
    • Tutorial on how to migrate APEL clients from EMI 2 to EMI 3 - available at APEL @ EGI CF 2014

• List of services failing EMI-2 tests:
  • as of Mach 7th - Download XLS file

3.1 EGI UMD usage survey

• BROADCAST send on 28.05.2014:
  • Survey - please take the survery - IT IS STILL OPEN

Partial results

• 78 answers submitted (1/4 ~ 1/5 of production sites)
• ~60% of the sites are using UMD repositories to install at least a subset of their services
  • Of which, 92% (41) think that UMD is a useful service.
• Most important features of UMD
  • Unique repository containing most of the packages to install at site level
  • Protection from untested updates in the community repositories
  • Additional testing on top of developers certification
• Where to improve
  • Increase the frequency of the UMD releases, reduce the time to release new updates in the repositories
  • Test more the products, with more real users

Participate to the survey

• It can take from less than one minute to few minutes (let say 10-15 minutes)
• We will use the feedback collected by the survey to evolve the UMD services

3.2 Next meeting

July 28, 2014 - if enough participants available
