If you want to run manually the demmaccs script, you will have also to :
- Either stop the sen2agri-demmaccs service and timer:
sudo systemctl stop sen2agri-demmaccs.timer sen2agri-demmaccs
The demmaccs service is cleaning the /mnt/archive/demmaccs_tmp folder after its execution so if you launch manual executions, is highly probable (as demmaccs is executed every minute) to delete also the temporary files of your manual execution. This was implemented as these temporary folders are usually quite big and in some cases (forced stop of maccs or stop due to insufficient disk space) they remained on disk, requiring manual deletion.
2. Use another existing directory in your command instead of --working-dir /mnt/archive/demmaccs_tmp/
Hope this helps.
