          Report from CERN COD:

          1. Site: ITPA-LCG2 was failing GSTAT. Its publishing ScientificSL 5.0 which is not in the OS list used by GSTAT. In such case it should be the responsiblity of site/ROC to send a request to mailing list: roc-dev@lists.grid.sinica.edu.tw to add there required OS version in the list.

          AP, CE, IT, RU

          Issues from EGEE ROCs:
          1. None found. Actually, the pages displayed were completely empty, so I suspect a malfunctioning of the portal (reported)

        • <big> EGEE issues coming from ROC reports </big>
          1. (ROC France): Some site administrators complained because their e-mail address was added to a VO mailing-list without their agreement. The VO has been contacted and the problem is being solved, but that incident raises the more general problem of SPAM generated by the project itself. Could we agree in a good administration rule of mailing-list ? At least, except for some obvious and mandatory mailing-lists, an actor should have the possibility to unregister from any mailing-list by him/herself. The way to unregister should be made clear by the mailing list.

          2. (ROC DECH): Please reopen action item 150. The problem is still present. see GGUS #33850.

          3. (ROC SEE): https://gus.fzk.de/ws/ticket_info.php?ticket=33697 is long overdue, please put some pressure on the corresponding support unit to respond.

          4. (ROC SEE): LCG-TAU still has some problems, thus its is now in downtime for the next 7 days in order to upgrade to the latest gLite release.

          5. (ROC SWE): We would like to have an update Top-BDII failover awareness on gLite client tools. Is it possible to confgiure several BDIIs in form of a list with yaim?

          6. (ROC UKI): GGUS should respond whether the UKI-SOUTHGRID-CAM-HEP problem of 100 mails for the same ticket is a bug.

          7. (ROC UKI): There have been many complaints in UKI about the move to the need to complete the site reports every day. Site admins often fill out the report for the week in one go and this seems a sensible approach - at least they should be able to choose. Several sites have indicated that they will stop filling out the reports in this new format. On the positive side the new interface seems better with the graphical representation of downtime etc. However, it would be very welcome if the colours used between tools were consistent. Previously grey represented downtime and red a failure... now we have black. Sites would also like to see the past history for the report so they can cross reference previous failures which is a feature lost in this upgrade.

          8. (ROC UKI): The move to validating every use of a certificate on a site is becoming tedious. Is this a feature of the browser settings or does everyone get greeted with constant requests to use their certifcate? Is it possible to have a compact view and a detailed view of site problems? I can not see correlations between sites anymore.
        • <big> gLite Release News</big>
          1. gLite 3.1 Update18, announced for last week, is being released to production right now.

            • DPM 1.6.7-4

              • improved ACL management for srmMkdir command
            • UI/WN/VOBOX
              • lcg-tags non longer produces Globus warnings suppressed
              • voms-admin client 2.0.6-1 providing ACL support on command line
            • vdt_globus_essentials (affecting several services and notably the CE)

          Time at WLCG T0 and T1 sites.

        • <big> CCRC'08 Operational Review </big>
          • There will be a test of the Tier0 to Tier1 Optical Private Networks backup links from 15.00 to 19.00 CEST (13.00 to 17.00 UTC) on Wednesday 9 April.
            The plan of the test is here:
            RAL will be unreachable for 15-20 minutes between 16:45 and 17:15 CEST
            PIC will be unreachable for 15-20 minutes between 17:15 and 17:45 CEST
            The goal of the maintenance is to verify that all the backup solutions work as expected. The T1s with a backup link should be up all the time, but at the moment we cannot guarantee that it will be the case and there may be outages at any time for any Tier1. It would be appreciated if experiments could particularly exercise their links as much as possible during the test period.

        • <big> Alice report </big>
          No report received before the meeting.
        • <big> Atlas report </big>
          1. new version of DPM:
            in today' s meeting I would like to know the status of the DPM server version fixing the ACL problem. In particular, I would like to know if this has been released to production and when (it should have been last Wednesday). Also, I would like to know the exact version+patch number so that I can refer to it in the proper manner.
            ATLAS T2s need the patch to start running production on SRMv2 and we would like to push the deployment of the patch ASAP.
            Could you make sure someone can provide the infos mentioned above at today's meeting? Both Alessandro and I will be present.

            ANSWER: The version is DPM 1.6.7-4; it is in PPS and will be released to production today

          2. ATLAS sites with lcg-utils for SRM2:
            we have developped a SAM test to see which version of lcg-utils has been installed on the WN of the ATLAS supporting sites.
            The results can be seen in the sam web page, selecting ATLAS VO, CE, CE-sft-lcg-version
            SAM link
            The sites that give ERROR in this test didn't upgrade to the SRM2 compatible version of lcg-utils.
            Hope this could help in following the action of having, in all the ATLAS supporting sites, the WN upgraded to SRM2
