How to upload a DANS archive to the grid

  • create a new directory with the name of the archive. As an example we use the 'Crome' archive. We refer to the name of the archive using the environment variable '$ARCHIVE' :
 $ export ARCHIVE=Crome
 $ mkdir -p ~/dans/$ARCHIVE/
  • In this directory create another directory with the same name; this directory will contain the list of files and directories that need to be uploaded
 $ cd ~/dans/$ARCHIVE
 $ mkdir $ARCHIVE
  • copy over the scripts from the repository
 $ cp -a ~/dans/scripts/* .
  • generate a sorted list of files. Note: All further actions are done based on this list!
 $ find -L $ARCHIVE -type f | sort > ${ARCHIVE}-files.txt
  • check the list of files , remove any entries such as '.Trash' folders if desired.
  • generate a list of tarball.lst files. Each tarball.lst file contains a subset of entries from the ${ARCHIVE}-files.txt file that , when tarred up into a single .tar file, is roughly 8 GB in size. The output files are named '$ARCHIVE-<N>.tar.lst' where <N> is a 4 digit counter starting at 1:
 $ ./gen-tar-list ${ARCHIVE}-files.txt
 Crome-0001.tar.lst
 Crome-0002.tar.lst
 ...
 Crome-0072.tar.lst
  • Now the final big step: run the 'upload-tar' script, which will
    • generate the tarballs
    • generate md5 checksums for all files in each tarball
    • upload each tarball to the grid.

Note: For this step a valid grid proxy is required!
