Weekly OSG, EGEE, WLCG infrastructure coordination meeting.
We discuss the weekly running of the production grid infrastructure based on weekly reports from the attendees. The reported issues are discussed, assigned to the relevant teams, followed up and escalated when needed. The meeting is also the forum for the sites to get a summary of the weekly WLCG activities and plans

  • <big> UPDATE: next versions of YAIM: content and timelines </big>
    Clarification: Once YAIM 3.1.1 is released (expected mid July), the previous versions of YAIM will not be further developed or maintained. This means that YAIM bug fixing will only be done in versions equal or higher than 3.1.1. the new yaim can use old site-info.def. The way site-info.def is handled hasn't changed. In general, the new yaim doesn't introduce big changes for the site admins since the yaim command is already present from yaim 3.0.1.

  • <big> YAIM 3.0.1-22 and SGM/PRD accounts </big>
    • glite-yaim=3.0.1-22 (gLite 3.0.2 Update 27) allows "sgm" and/or "prd" users to be mapped to the traditional static accounts or to their own sets of pool accounts.
      Pool accounts are better w.r.t. the audit trail on the CE and WN.
      The use of pool accounts can be decided per VO and per account type: YAIM will discover which sort of accounts has been put into users.conf for sgm and/or prd users and map those users accordingly.
      The LHC experiments have been asked to adapt their software installation procedures to cope with the possible use of sgm pool accounts at sites.
      LHCb were the only ones to respond so far: in principle their procedure is ready, but they request sites not to switch to sgm accounts during the summer holidays, when the available expertise to debug problems is much reduced.
  • <big> Staged upgrade of BDIIs to gLite 3.0.2 Update 27</big>
    Dear all,

    gLite 3.0.2 Update 27 includes fixes to the Glue schema:
    The new version of glue-schema updates to Glue version 1.3. The top-level BDIIs should be updated first, followed by the sites BDIIs and then the GRISs. Only when all the nodes have been updated, new information can be published.
    As discussed at this week's operations meeting, we propose a coordinated staged deployment of this fix to the production BDIIs:
    • Step 1: upgrade ONLY all top level BDIIs in the next week, deadline: the end of next Monday 9th of July
    • Step 2: upgrade site BDIIs, starting from Tuesday 10th of July (a reminder will be given at next Monday's operations meeting and broadcasted after).

    PLEASE, ALL PRODUCTION SITES: don't upgrade your site BDII yet, wait till Tuesday 10th of July
    (In case your site has been already upgraded, we are presently testing what would be the effects of this (site BDII upgraded and top level BDII not upgraded) so we can inform the VOs and find a workaround).
  • <big> EGEE issues coming from ROC reports </big>
    • ROC AP:
      • For information: GStat migration to GOCDB3 is not complete, so recent site changes have not propagated to Gstat. This work is scheduled be completed by July 10th. op level bdii is scheduled to be upgraded to 1.3 glue Schema later today.
    • ROC France:
      • Comments on CIC portal
        In the weekly ROC report, we can fill the T1 availability text field, but it''s impossible to consult it afterwards. Please update the consultation of ROC report to make available this field.
      • official URLs to be used for a TOP BDII configuration
        Is there somewhere an official repository (web page) with the official URLs to be used for a TOP BDII configuration. We mean the value of BDII_UPDATE_URL providing the list of all the production sites, and BDII_UPDATE_LDIF providing the list ldap filtering rules built by FCR.
    • ROC SEE:
      • Release notes for Update 27 are not correct (reconfiguration of BDII is not mentioned in Update 27 Release notes, but it is apparently necessary). See this ticket for details:
