        • Eventually ADC foresee having this distribution model also apply to secondary copies of AODs (so still maintain shares of primary AOD distribution in cloud)
      • general overview talk regarding PD2P can be found here
    • published site installed resource capacity information to be investigated and confirmed against WLCG information [20100928]

        • this problem will be on the agenda for the next ADC monitoring meeting scheduled for next week
        • Previously Reported Information on this topic:
          • escalate query to ATLAS dashboard support regarding missing CA-SCINET-T2 site in the ARDA dashboard production activity display [20100216]
      • CA-VICTORIA-WESTGRID-T2 site missing from the ATLAS dashboard SAM Visualization page [20100824]

        • production queue kept in test state pending investigation of fortran runtime error "permission denied" within software release area (20100708) [SOLVED]
          • resolved by changing WN client NFS mounts to v3 from original NFSv4 (root cause within NFSv4 still unknown) [OPEN]
      • ROOTSYS truncated at 127 characters issue [20100608]
        • http://savannah.cern.ch/bugs/?68546 (open)
        • currently affecting Victoria (Tier3) and CA-SCINET-T2

        • related issue: user build jobs failing at CA-SCINET-T2 [20100511]
          • follow-up with site in regards to missing rpm installation; missing rpms added but problem is still occurring [20100518]
      • reviewing draft Squad How-To and providing feedback [20100407]
        • also contains useful information for sites
      • ongoing discussions with ADC experts regarding regional production activity and how to accommodate it cleanly within both the production system and the CA cloud and site operations [20100316]
      • running out of jobs at TRIUMF (and other CA cloud sites other than CA-SCINET-T2) [20100402]
        • "The problem may be due to the jet/group production task. Since these jobs have high priority, they are being sent to CA cloud, to the exclusion of lower prio jobs. Of course, they can only run at one site. So, other sites are running empty. Unanticipated side effect of running the task only at CA-SCINET-T2! Let me think how to solve it." K. De (ADC)
      • request submitted to Panda team for functionality to set site Panda queues offline automatically based upon scheduled outages/availability [20100216]
    • Outstanding Actions to Do:
      • follow-up information system publishing by dCache sites and use of FileStager within GangaRobot [20100111]
        • ie. dcap missing from TRIUMF and CA-ALBERTA-WESTGRID-T2 and so uses lcg-cp.

  • Squid Deployment [20101012]
    • CA cloud Frontier and Squid deployment information (versions and network information)
    • SAM tests: (CA Link), (Aus Link): currently status as of this morning (WARN is ok) [2011012]
      • CA-ALBERTA-WESTGRID-T2 OK (both for local squid and backup to SFU)
      • CA-SCINET-T2: OK (both for local squid and backup to SFU)
      • CA-VICTORIA-WESTGRID-T2 OK (both for local squid and backup to CA-ALBERTA-WESTGRID-T2)
      • SFU-LCG2 OK (both CEs; both for local squid and backup to CA-VICTORIA-WESTGRID-T2)
      • ATLAS_AUSTRALIA - OK (OK for local squid and backup to CA-VICTORIA-WESTGRID-T2)
      • TRIUMF-LCG2 OK (ce1) OK (ce2) (local Frontier launchpad and BNL as backup)
      • VICTORIA-LCG2 OK (OK for local squid and backup to CA-VICTORIA-WESTGRID-T2)
