    Recording of the meeting
      • 4:01 PM 4:30 PM
        EGEE Items 29m
        • <big> Grid-Operator-on-Duty handover </big>
          From: DECH + SouthEast Europe
          To: CERN + France

          Report from SouthEast Europe:
          • List of unresponsive sites:
            • None
          • Problems Encountered during shift:
            • Again new alarms for nodes which have already been in SD
            • The new version of the https://lcg-sam.cern.ch:8443/sam/sam.py?... looks more attractive but unfortunately it is not so clear and easy to deal with those cases when an alarm is in ERROR but the last SAM test show that the corresponding service is still OK.
          Report from DECH Europe :
          • List of unresponsive sites:
            • None
          • Problems Encountered during shift:
            • GGUS ticket: 46448
              Site USCMS-FNAL-WC1 is an OSG site. Alarms should not be raised. But it happened this week when they started to publish their resources in a resource group. Seems to be fixed now.
            • GGUS ticket: 46448
              The alarm FTS-infosites on fts-t1import.cern.ch is failing due to the fact that the middleware does not foresee the current production scenario in use at CERN. Developers are aware, a bug has been opened and it will be like this until the bug is fixed (Savannah bug #46083)

        • <big> EGEE issues coming from ROC reports </big>
          • SWE ROC:
            • We would like to know the status of the new gLite "authorization framework", the "framework to identify local T2 users" at a site.
          • UKI ROC:
            • Got a GGUS ticket (46475) but believe tickets should not apply. Still waiting for feedback on this.
              This CE is flagged as "Not in Production" in the GOCDB. Monitoring is turned on for troubleshooting purposes during commissioning. Our understanding is that GGUS ticketing does not apply in these circumstances.
        • <big>Grid Service Interventions </big>
          Link to CIC Portal (broadcasts/news), scheduled downtimes (GOCDB) and CERN IT Status Board

          Please consult the URLs above for details.

          In particular, the following sites requested that these downtimes be reported here:

        • <big> Update on SL5 </big>
          Speaker: Oliver Keeble (CERN)
      • 4:30 PM 5:00 PM
        WLCG Items 30m
        • <big> WLCG issues coming from ROC reports </big>
          1. DECH: FZK-LCG2: New instance for FTS (2.1) is in production. The two instances will run in parallel for some time until all experiments have switched to the new instance.
            The new Service name is fts-fzk.gridka.de
          2. <be> DECH: CMS User with voms group /cms/dcms cannot run with at CERN and various other sites, see https://gus.fzk.de/ws/ticket_info.php?ticket=46019.
            Not supporting this group and probably a lot of other groups makes no sense or the groups are waste. In my opinion, when one site supports a VO it should use wildcards to ensure the support for all users proxies. If it does not use wildcards the queues in the information system should be published only for the supported groups and roles.
            Is there a standard way how to deal with this situation? Or is it possible to exclude special group or roles in the information system (blacklist)?
        • <big> Wiki page containing FTM Endpoints </big>
          Can all tier-1 sites please keep the list of FTM endpoints up to date. The list is here: https://twiki.cern.ch/twiki/bin/view/LCG/LCGFTMEndpoints

          Note: This requirement will be replaced by information providers publishing the end-points into the information system.

      • 5:00 PM 5:30 PM
        OSG Items 30m
        Speaker: Rob Quick (OSG - Indiana University)
        • Discussion of open tickets for OSG
          Information taken from the weekly escalation reports.

          OSG did, indeed, re-remind Felipe Silva to answer on ggus #45094. What does one do in such cases? Maybe try to contact him offline, in case all GGUS/OSG ticketing systems' notifications end-up in his spam folder? The submitter still expects an answer.

          There will be a GGUS-OSG tel. meeting, latest proposed date March 12th. Invitation people and background:

          Please say if Thursday March 12th at 16hrs CET suits you before I create
          an agenda and book a room for a meeting on FNAL (in March) and BNL (in
          April) exiting GOCDB and the repercussions of this into ATLAS and CMS
          problem reporting via GGUS Direct Site Notification.
          The previous 2 suggested dates didn't work for some of you.
          CMS participation is also important.
