While sync_to_disk is executed rsync or cp copies content of path to hdd.path. Logging of this is done at $LOG2RAM_LOG, which is located at $RAM_LOG. In case of executing sync_to_disk inside stop) command, subsequently $RAM_LOG will be unmounted. Changes are lost. The fix separately copies $LOG2RAM_LOG to $HDD_LOG to keep the sync_to_disk content.
