Is it possible that the application will not clean nilfs_cleanerd segments? I had this situation and the USB disk filled up to 100%. My configuration file: # Protection period in second. protection_period 1800 # Minimum number of clean segments # 0 = continuous cleaning # > 0 = pause cleaning until less segments are available min_clean_segments 40% # Maximum number of clean segments max_clean_segments 60% Åukasz WÃjcicki -- To unsubscribe from this list: send the line "unsubscribe linux-nilfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
