我已经将一个160Gb磁盘克隆到1TB磁盘上。
看到这里的确切的细节。 克隆Ubuntu的Linux硬盘
我想要使用整个磁盘。
我如何获得卷使用整个磁盘。
在前面的post里有一些build议，我已经search了一下，但是我不确定什么是最好的前进方向。
谢谢

您可以通过以下方式增长LVM：
pvresize或 上面的磁盘信息有点不清楚，所以我会忽略它，给你一个程序的一般描述。 如果你的1TB磁盘是空的，除了LVM分区，那么你可以简单地：
fdisk来增加分区的大小 pvresize增长LVM PV以匹配分区的大小。 如果您将磁盘上的LVM PV与其他分区混合，请不要这样做。 但是如果坚持，可以创build一个覆盖额外空间的额外分区，然后将其添加到卷组中：
pvcreate /dev/sd?? vgextend vg0 /dev/sd??
