How to upload a DANS archive to the grid
Note: as a convention, commands that need to be typed in are preceded by a UNIX prompt-sign '$' . Output if shown without a preceding prompt sign.
- create a new directory with the name of the archive. As an example we use the 'Crome' archive. We refer to the name of the archive using the environment variable '${ARCHIVE}' :
$ export ARCHIVE=Crome
$ mkdir -p ~/dans/${ARCHIVE}
- copy over the scripts from the repository
$ cd ~/dans/${ARCHIVE}
$ cp -a ~/dans/scripts/* .
- 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
$ mkdir ${ARCHIVE}
- in this second ${ARCHIVE} directory, create a list of all files and directories that need to be uploaded. If an entire directory needs to be uploaded then create a symlink to it. For the 'Crome' archive the following command was used to create the symlinks:
$ for i in <fullpath>/Crome/crome*/ ; do echo ln -fs $i ; done
- 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.
- Use the gen-tar-list script to generate a list of tarball.lst files. Each tarball.lst file contains a subset of entries from the ${ARCHIVE}-files.txt file that , when tarred up into a single .tar file, is at least 8 GB in size. The output files are named '${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-0073.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. It is often useful to run the next command inside a screen session.
Note: For this step a valid grid proxy is required!
$ ./upload-tar

Moving ${ARCHIVE}-0073.tar.lst and ${ARCHIVE}-0073.tar.md5sum to directory "done"
For each tarball that is successfully processed the '${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 '${ARCHIVE}-<N>.tar.lst' files until all have been moved to the 'done' directory.
For more details on the usage of the 'upload-tar' script , see DANS Job Scripts.
- Check the contents of the 'done' directory , especially the contents of the '${ARCHIVE}-<N>.tar.md5sum' files:
$ cat done/${ARCHIVE}-0001.tar.md5sum

# Crome-0001.tar END
By combining all '${ARCHIVE}-0001.tar.md5sum' files a full list of all md5sums can be generated and compared to the output of an 'md5deep' command:
$ for i in done/${ARCHIVE}-*.tar.md5sum ; do grep -v '#' $i ; done | sort > total.md5sum
- After verifying that all '${ARCHIVE}-0001.tar.md5sum' files are correct, move them (or symlink them) to another directory 'checksums'. The latter directory is used by the 'compare-checksums' script from Phase 3: Verifying data.
$ mkdir checksums $ cp done/*.tar.md5sum checksums
- Once the upload has completed successfully you can proceed to Phase2: Compressing Data.
