SAM CMS Remote Stageout test

Maintainer: Nicolò Magini

Overview

Checks

• that the CMS software directory is defined, existing and readable
• that the CMS software initialisation script (cmsset_default.sh) exists and can be sourced without errors
• that Python 2.6 can be found
• that the stage out via lcg-cp succeeds to at least one destination site
• that the cleanup of the test file succeeds

Stage out logic

• Test the site configuration
  • test that CMS_PATH exists in the environment
  • test that can load the site local configuration
  • test that the stage out command srmv2-lcg (corresponding to the lcg-cp command) is defined
• Translate /store/user/sam/SAM/RemoteStageOutTest-pid-date into a PFN using the appropriate PFN prefix for the chosen destination SE
  • This target directory should be writable for the /cms/Role=lcgadmin role
  • FIXME: Currently, the LFN is temporarily in the /store/user/magini directory, pending configuration of /store/user/sam on the destination SEs
  • The LFN2PFN conversion is hard-coded in the test code, so that we don't need to query the PhEDEx datasvc. We rely on the fact that the destination sites will not change their /store/user path without warning us.
• Test the remote stage out
  • test that a stage out implementation can be retrieved
  • test that the stage out can be performed normally to at least one of three sites
    • The current destination sites/endpoints are:
      • T2_CH_CERN: srm-eos.cms.cern.ch
      • T2_IT_Pisa: stormfe1.pi.infn.it
      • T2_US_Nebraska: dcache07.unl.edu
    • The order in which the destination endpoints are selected for stageout is random. As soon as stageout to one endpoint succeeds, the test returns OK.
• Test that the test file can be cleaned up from the remote SE
  • test that a stage out implementation can be retrieved
  • test that the file removal succeeds
