Dans Data Upload

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.

This script will take a long time to run, depending on how many tarballs there are.

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

 $ ./upload-tar
 Checksumming tarball contents
 Generating ${ARCHIVE}-0001.tar
 ...

For each tarball that is successfully processed the '${ARCHIVE}-<N>.tar.lst' file is moved to a separate directory 'done' . This way the 'upload-tar' script can be stopped and restarted at will, as it will continue processing '${ARCHIVE}-<N>.tar.lst' files until all have been moved to the 'done' directory.
