【已暴力解决】为神马整个硬盘只能用一部分，其他的看不见也不能用呢？【没有windows分区】

[allengo]

ubuntu单系统，安装的时候选了自动分区，然后鬼使神差的输了个30%，现在能用的只有12GB，还有40多GB
看不见也用不了，请问各位大大，这是为神马啊为神马

看出，系统是自动为lz用了LVM的文件格式来划分硬盘，而LVM是把几个分区联合起来当一个分区使用的，有它的存在价值。此case可以有解，不过不适合新手

唯一建议，楼主最好重装系统，并参照网上的ubuntu安装攻略，这次就不要自己摸索了

[hiphen]

一般个人使用，系统会给你分配ext3或ext4文件格式的
LVM通常只出现在服务器的管理上

谢啦谢啦，我还是重装吧，早知道就手动分区了
