Von: Operations of NGI-DE [1] Im Auftrag von Dimitri Nilsen
Gesendet: Dienstag, 31. Juli 2012 18:20
An: NGI-DE-OPERATIONS@LISTSERV.DFN.DE
Betreff: Publishing User DNs
Dear Sites,
according to "Grid Policy on the Handling of User-Level Job Accounting Data" sites should publish User DNs for accounting
Please ensure you have publishGlobalUserName="yes" in publisher-config.xml at your apel box
Status of releases
Sites that support WLCG VOs should update to EMI release until 1st October. At least to EMI 1. gLite releases should not longer be  
supported. We at KIT are currently updating our services (WMSs, sBDIIs, CREAMs). WNs will follow. Dimitri will send around a list 
of versions and deadlines. 1st October will be a little bit unrealistic.

- one reason for the low performance/avail/relia: SAM test failed over some days->site was offline. This was caused by monitoring 
problem. Aachen had the same problem. Now it is working again.
- one of the file system of one of our pools crashed, we lost 15TB of data whitch we were able to partially restore. Interesting: 
After this we had to put the site offline from time to time because the dataflow of the restore process was so high that jobs were 
blocked.-> Additional downtime to restore the files was needed.
- We need a downtime at the end of the month to update dCache to 1.9.12, to instal CERNVMFS and we did a TORQUE update on CREAMS. 
But this TORQUE version blocked proxies. We did downgrade. For the old gLite and EMI versions there is still an old version of a 
TORQUE package in the repository. Recommendation from Dimitri: An email to the rollout list should be written. Next week in Prague 
Dimitri can also ask the people from EMI. 
- added some WNS
- Migration to EMI 2 started, CREAM 3 in test phase
  • Uni Mainz-Maigrid
  • Uni Siegen
