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.
