MDSS migration

  • "man mdss" for command usage
  • Use copyq queue for migration of data to MDSS
  • If there are lots of small files please tar/gzip them up
  • An example script to migrate a year's worth of data, with one job submits itself to process the next month (run for a month first to work out the elapsed time required)
