          • 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]

          • 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

      • 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 [20101005]
    • 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) [2011005]

      • 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)
