EGEE Ops' Minutes Mon 02 Nov 2009

PPS Reports and Issues

• Please find Issues from EGEE ROCs and general info in: https://twiki.cern.ch/twiki/bin/view/LCG/OpsMeetingPps

• First official staged rollout update last week, to the early adopters sites (previous release testing sites); deployed at 4 sites out of 5. Only new version of lcg-infosites, it is a real release. New release pages already produced. One question raised, core services pointing to PPS instances? Yes, let’s leave it like that at the moment, and gradually move to production ones. Date to change to production ones? Nothing set yet, we are only exercising the process in the old PPS environment, so no real change yet. Antonio hopes to involve production sites by the end of the year.

gLite Release News

• Please find gLite release news in: https://twiki.cern.ch/twiki/bin/view/LCG/OpsMeetingGliteReleases

• Release of UPDATE 58 to gLite 3. 1, restoring the components rolled back in previous update and not affected by the critical issue
• lcg-vomscerts, new method is supposed to replace tit, why are we still releasing it? We still have to distribute it because of dependencies on WMS that are being worked out.

EGEE Items From ROC Reports

• DECH, GGUS ticket #47944 (sBDII SAM fests failing for FZK-LCG2 though GIIS is working fine) no news: Gstat developer (Joanna) removed from support list, now back in and checking this ticket.
• Italy: all RBs have been retired; all WMS have been upgraded (WMS @ INFN-FERRARA update is in progress, the WMS is closed).
• SEE: There are a couple of concerns from our region about the glite-SWAT utilities/tools. The most important/critical of them are:
  • Does the tool use the user's credentials (without their knowledge)? It does not use user credentials, just runs scripts in wn to get info about wn itself
  • If so, what about the privacy of user's data? not applicable (see previous answer)
  • Can this tool make modifications to the user's job environment? no, The tool does not export anything back into the job environment; results are stored in job directory of job user
  • Is it possible that a failure of the monitoring tool could lead to the user's job failing? So far we did not have that case but it could happen; development was careful to prevent this; mx 30 seconds and if no results it will be destroyed by itself.
• (From the previous meeting) Italy: Which is the version for each Storage Element implementation to be compliant with the "Usage of Glue Schema v1.3 for WLCG Installed Capacity information"? As ROC, we could push and follow the upgrade of the old version and validate the published data. The Baseline versions of services and client tools for WLCG operations (https://twiki.cern.ch/twiki/bin/view/LCG/WLCGBaselineVersions) seems to be update last 02-Jun-2009. This useful page should be update more frequently (at every gLite update?) just to be sure that the recommendations are not out of date. ANSWER: We have contacted teh WLCG team and they will update this page to include the SE version compliant with Glue 1.3. Additionally we are building the EGEE baseline and have plans to update it automatically with each release.

Grid Service Interventions

• Due to improvement the service, it is possible that Monday, 2 November the accounting portal at www3.egee.cesga.es suffer intermittently cutting of service for a few minutes....
• The GGUS system will go down for an unscheduled reboot today at 12:30 UTC

CREAM-CE Deployment

CREAM CE SAM tests are in production, non critical. Please start to have a look at the results (need to check "NA - no status available").
Timeline? For wlcg now, no more details given.

Miscellaneous

• There are still a few RBs and old versions of WMS out there: Please check this page for the details: http://straylen.web.cern.ch/straylen/wms-count.txt
• Please remember to keep the monthly availability comments Wiki up-to-date: https://twiki.cern.ch/twiki/bin/view/EGEE/MonthlyAvailability
• Significant Update to SA1 OAT Nagios Release made today.
• DECH: complaints from Nagios sites receiving GGUS tickets, what is this? we were not aware of anything related; 4150 and 4159, tickets opened against the regional dashboard. Wen will send more information to debug this incident.
• Firewall port at CERN that allows direct update of job status to CREAM-CE is closed, so a fallback mechanism which takes a lot longer is used. This only affects timing, not functionality, but the problem is in the process of being fixed.
