- Download and install the python transfer script from http://www.physics.gla.ac.uk/~graeme/scripts/index.shtml#filetransfer.
- Initialise your grid proxy certificates and myproxy certificate:
$ export MYPROXY_SERVER=lcgrbp01.gridpp.rl.ac.uk $ grid-proxy-init -valid 48:00 # This needs to be long enough to live through the transfer $ myproxy-init -d
- Submit a 1TB transfer test as 1000x1GB files (FTS cannot accept more that ~1000 files in a single request, by default). N.B. The --ignore-status-error option is required as there's a bug in FTS causing glite-transfer-status -l to have a non-zero exit code when transferring more than ~50 files.
$ filetransfer.py --number=1000 --background --delete --ignore-status-error \ srm://dcache.gridpp.rl.ac.uk:8443/pnfs/gridpp.rl.ac.uk/data/dteam/tfr2tier2/canned1G \ srm://my.srm.host:8443/pnfs/domain/data/dteam/ftstest
If you are testing your DPM from Glasgow then
$ filetransfer.py --number=1000 --background --delete --ignore-status-error \ srm://se2-gla.scotgrid.ac.uk:8443/dpm/scotgrid.ac.uk/data/dteam/tfr2tier2/canned1G \ srm://my.srm.host:8443/dpm/domain/home/dteam/ftstest
The --background means the script runs in the background and can be monitored with tail -f on its logfile (filetransfer.log by default). This is good if you're logging in from home to check on progress!
