LFC launching at AGLT2

  • See ChecklistForLaunchOfLFC
  • last week
    • Question about the production proxy. For AGLT2, both atlas and usatlas production roles need to map to usatlas1. Need to test with Nurcan's script.
    • One concern is whether gplazma mappings get updated correctly - storage authz db.
    • John: will be creating a new account w/ atlas production role. condor-g submit can point to a specific proxy. status?
    • DQ2 change should be simple, will involve a ToA change.
  • new status
    • All DQ2 related issues seems to working.
    • Problem with getting pilots to run correctly. Is there a problem with worker node client?
    • Fails to import lfc - cannot open shared object file. Something not quite right with the environment.
    • What about the other pythons installed in $APP/atlas_app? Interference? Mixing 64 bit and 32 bit, possibly?
    • Xin will re-install the python in $APP/atlas_app, making sure its 32 bit.

LFC installation

  • VDT release, other updates to InstallLFConOSG?
  • No problems reported. Updates for deleting a file.

LFC-based data management tools (Patrick, Charles)

  • File-based deletion working. Scripts from Vincent Garrone for dataset level deletion.
  • User dataset deletion. This will probably be a challenge? How is it handled in the LCG?
