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

• Generate the tarballs, generated md5 checksums for all files in each tarball and upload them to the grid. Note: For this step a valid grid proxy is required!

 $ ./upload-tar
