Hi, I tested Online Defrag by using the new code. When I have space left which is less than 40M, I can't use e4defrag function. Does the Online Defragmentation need some space left which is greater than a value? 40M? -- Regards Zhang Xiliang -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
