EGEE Items

Grid Operator Hand Over on Duty

From	ROC Central Europe
To	ROC Northern Europe

• From Malgorzata's written report, there were no problems from last week that hadn't been handled properly.
• However, Michaela complained that SEE hadn't reacted to many tickets (9 expired tickets), and she also had a mail issue with the dashboard (no handover mail received, only visible in dashboard). By e-mail, she added the following:
  • GGUS:49838 Problem in solving APEL issue since one month, node should maybe go into downtime.
  • GGUS:49754 ROD was clearly helping, but site couldn't solve problem after one month, should clearly go into downtime.
• Steve asked Marios from SEE to investigate the ticket problem, and he agreed to do so.
• Steve requested that during next week's handover, particular attention is paid to the CIC portal (dashboard) bits to see whether Michaela's problem was a one-off, or something that needs fixing.

PPS Reports and Issues

• Antonio had nothing notable to report

gLite Release News

• Please find gLite release news in: https://twiki.cern.ch/twiki/bin/view/LCG/OpsMeetingGliteReleases
• glite 3.2 update 0.4 (SL5 LFC, DPM & GFAl libraries) was released to production today, together with a new version of YAIM core, and a new WN myproxy client. An important 3.2 BDII patch is also included (avoids losing some sites under certain conditions). BDIIs on SL4 are not affected.

Grid Service Interventions

• Please consult links on the agenda page - there are quite a few scheduled downtimes!

Various points about S/W versions

• VOMS-client incompatibility on the way!
  • A new client which is not backward-compatible with gLite 3.0 VOMS servers is on its way. The list of problematic VOMS servers in the agenda is outdated (e.g. UK/I have already upgraded) - Steve will ensure that next week's list reflects the current status.
• Legacy gLite versions on CEs and WNs
  • General call for all sites to stay abreast of S/W versions. Once the default SAM DPM is upgraded, some sites will fail replica management tests (see SAM Validation portal for the list). Gareth said that one site in particular would rather retire some old hardware than upgrade (Royal Holloway UKI-LT2-RHUL). Steve thought that the official policy should be that the site (or offending CE) should disappear.

OSG Items

• Maria was not present, and Kyle had nothing specific to bring up.
