Description

Until now, repack and archival of new files were carried out on the same tapepool. This could lead to the user's new archive files being mixed on the same tape as the old repack files, reducing performance during retrieve. With the latest version of CTA, we can create dedicated REPACK archive routes in order to repack to separate tapepools. We have modified ATRESYS to accommodate this new repacking method. This presentation gives a brief explanation of the new actions implemented in ATRESYS. A quick demonstration of a REPACK with ATRESYS will be presented to visualise the workflow.
