我运行

Linux客户端的VM Player,我想知道如何扩展磁盘？在VM播放器中,我提供了更多的磁盘空间,但我不确定如何将新的磁盘空间安装/扩展/连接到系统.

我的旧磁盘空间是14GB

[root@localhost ~]# df -h /

Filesystem Size Used Avail Use% Mounted on

/dev/mapper/VolGroup-lv_root

14G 4.5G 8.2G 36% /

然后我扩展了它,现在我看到sda2是新的空间？

[root@localhost ~]# fdisk -l

Disk /dev/sda: 128.8 GB,128849018880 bytes

255 heads,63 sectors/track,15665 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

我需要先安装新空间吗？

resize2fs -p /dev/mapper/VolGroup-lv_root 108849018880

resize2fs 1.41.12 (17-May-2010)

The containing partition (or device) is only 3549184 (4k) blocks.

You requested a new size of 1474836480 blocks.

resize2fs -p /dev/mapper/VolGroup-lv_root 128849018880

resize2fs 1.41.12 (17-May-2010)

resize2fs: Invalid new size: 128849018880

[root@localhost ~]# lvextend -L+90GB /dev/mapper/VolGroup-lv_root

Extending logical volume lv_root to 103.54 GiB

Insufficient free space: 23040 extents needed,but only 0 available

[root@localhost ~]# lvextend -L90GB /dev/mapper/VolGroup-lv_root

Extending logical volume lv_root to 90.00 GiB

编辑：

所以在尝试pvcreate / vgextend后到目前为止还没有任何工作.我猜测从VM Player添加的新磁盘空间没有出现？

pvscan
