FileStager

Requirements for using the File Stager

• A valid grid certificate

• Grid environment setup correctly:

     source /global/ices/lcg/glite3.2.4/external/etc/profile.d/grid-env.sh

Troubleshooting

    Error with lcg_cp utility!Error message: Some error message from the Lcg_util middleware
    Checking file size:File does not exist, or problems with gfal library.

This is usually indication that no valid certificate exists, or that the grid environment is not setup correctly. Try:

    echo $LCG_LOCATION

to see if this environment variable is set correctly. It should point to some directory like

   /global/ices/lcg/glite3.2.4/lcg

Also try:

  lcg-cp -v --vo lhcb srm://aFiletoStage file:/tmp/localFileCopy

If this isn't working correctly, ask a grid expert to solve the problem.

   No permission to write in temporary directory <someusername>. Switching back to default <$TMPDIR>, or else </tmp>.
   Default tmpdir set to <someusername>

The temporary directory is where the staged Grid files are stored, in the course of the job execution.

You can override the default location by including the following line in the jobOption file

   FileStagerSvc().BaseTmpdir="/some/temp/directory/with/sufficient/space"
